ENERGY OPTIMIZATION IN TISSUE DRYING

WITH Prime Dry Hood E ELECTRICALLY HEATED YANKEE HOOD

Bearing in mind environmental sustainability and the cost of energy, Prime Dry Hood E uses the same air system as gas- or steam-heated hoods, but with electric heaters replacing gas burners or steam heaters. The result is a system capable of achieving air temperatures of 400 - 450°C while increasing energy efficiency and reducing carbon dioxide emissions. To optimize energy cost and

energy security, a hybrid system is feasible. This can switch between gas and electric heating for hood air and enables a mill to select the fuel source which is most suitable for prevailing climatic conditions, the time of day, or changing tariffs for gas and electricity over a 24-hour period.

COMMENT IN THIS

elcome to the July-August issue of Pulp Paper & Logistics, which includes much about process control and conditioning monitoring. Which is appropriate because, as I write this, the news is being dominated by the heat wave in Europe. Reservoirs are at dangerously low levels, and water supply and its use is inevitably coming under even tighter scrutiny.

As an industry, water plays a key role in the production of pulp and paper and as supplies come under threat there is an increasing need to recover and recycle it. With the drive to net zero emissions, mills are looking to reduce the consumption of both chemicals and water while reducing both industrial emissions and waste.

Reducing fresh water consumption can be achieved through process optimisation, advanced water treatment filtration systems and the reuse of process water. However depending on the product being manufactured the entire mill’s water consumption may have to be evaluated, from start to finish to establish the correct course of action.

In our next issue, for September-October, we will be previewing the MIAC 2023 show in Lucca, Italy; tissue production and processing; raw materials; chemicals; and additives. Submissions should be with us no later than 19 September.

Massive changes planned by Stora Enso to improve its competitiveness

Swedish pulp and paper giant Stora Enso is planning to make itself leaner and more competitive with a number of restructuring plans for its operations and management.

The plans are aimed at improving profitability and focusing on growth markets, but will also mean thousands of job losses, which is why the process won’t start until negotiations with staff have been concluded.

The plans involve the closure of Stora Enso’s Sunila pulp mill in Finland, the De Hoop containerboard site in the Netherlands, one containerboard line at its Ostrołęka site in Poland, and the Näpi sawmill in Estonia, all with the loss of 600 employees.

To reduce and reorganise its group management there will be a planned reduction in employees. Some 1,300 are within the scope of the group function negotiations, with a planned reduction of about 300.

Stora Enso has recently completed most of the change negotiations in its Packaging Materials division with a reduction of around 250 jobs

in its management and support functions.

Although the changes are expected to cut annual sales by about €380 million, or about 3.3 percent of last year’s sales of €11.7 billion, yearly earnings before interest and tax are expected to increase by €110m. In the 2022 results, operational ebit was €1.9bn. The cost of restructuring could be up to €190m.

Annica Bresky, chief executive of Stora Enso, said: “These measures are of course very difficult and would not be proposed unless it

was absolutely necessary for our long-term competitiveness.

“We are at a critical juncture in our strategy advancement, and to further our market position an increased focus on capital allocation and decentralised empowerment is needed. This sadly means that assets suffering from challenged profitability would need to be closed, in combination with a more streamlined headquarter organisation.

“Through these actions we would be able to continue to deliver strategic growth from a more resilient and cost-efficient

business platform, better equipped to support the longterm growing demand for Stora Enso’s renewable products.”

● Stora Enso has opened a corrugated packaging plant at De Lier in the Netherlands. Expansion at the site, part of the recently-acquired De Jong Packaging group, adds a new, second factory and the equipping of the facility with two new corrugators to augment the existing two. As a result of the expansion, the site is now said to be the largest and most modern corrugated packaging facility in Europe.

Solenis completes $4.6bn acquisition of Diversey

Speciality chemicals supplier to the pulp and paper industry, Solenis has completed the US$4.6 billion acquisition of Diversey Holdings, a leading provider of hygiene, infection prevention and cleaning products and technology.

Based in Wilmington, Delaware, Solenis was acquired

by Platinum Equity in 2021. Bain Capital, the majority shareholder of Diversey, will hold a minority stake in Solenis as a result of this transaction.

Commenting on the sale chief executive of Solenis John Panichella commented: “This merger makes Solenis a more diversified company with

significantly increased scale, broader global reach and the ability to offer a ‘one-stop shop’ suite of solutions that meet customer demand and address water management, cleaning and hygiene issues on a global basis.

“Together, we have a foundation from which we can

continue to leverage our strong customer partnerships, leadingedge innovations and valueadded services to propel Solenis’ aggressive growth trajectory. With continued support from Platinum Equity, we are confident that we will maximise the promising opportunities ahead.”

UPM’s Paso de los Toros pulp mill inaugurated in Uruguay

UPM inaugurated its Paso de los Toros pulp mill in Central Uruguay in June with an event attended by the President of Uruguay Luis Lacalle Pou, several ministers and representatives of other stakeholders who have helped with the pulp and paper maker’s growth project in the country.

UPM chairman Henrik Ehrnrooth highlighted the consistent development of the sustainable Uruguayan forest industry and UPM’s operations in the country: “A key milestone for the Uruguayan forest industry was the Forestry Law which was enacted in 1987. The aim of this law was to diversify the country’s industrial portfolio,

ensuring sustainable land-use and protecting its natural forests. We can all see how well it has succeeded in all these goals and created a strong new export industry in Uruguay, sustainably.

“Today we celebrate UPM’s largest investment in our 150-year history. UPM’s first eucalyptus seedlings were planted in 1990. The path from then until today has been a great cooperation between authorities, UPM and its partners. The results of this cooperation will serve the interests of Uruguay and its people as well as UPM for decades to come.”

After four years of construction in Durazno, and despite the pandemic, the Paso de los Toros pulp mill was started up in April 2023 with the first pulp delivery

to customers following a month later. UPM’s third tree nursery in Sarandí del Yí started operating in the summer of 2022, and the new pulp terminal in Montevideo in October the same year. The total investment of US$3.47 billion covers the pulp mill and the port terminal as well as the local infrastructure in Paso de los Toros.

Insight from connected motors boosts mill efficiency Insight from motors boosts mill efficiency

Asurvey by ABB in March 2023 found that 92 percent of business leaders around the world see rising energy costs as a threat to competitiveness. High energy prices over the past year have put pressure on businesses to make hard decisions on how to allocate budgets. Many leaders have accepted lower profitability, while others are cutting back on people, marketing and infrastructure.

The energy crisis could also delay the achievement of Net Zero targets. Of the respondents that reported, 58 percent said

Erich Labuda, president of ABB Motion Services, explores how two pulp and paper operators in Sweden are using motor data to improve energy efficiency, cut consumption and reduce carbon dioxide emissions

that the energy crisis will delay their decarbonisation plans by up to five years. In addition, 61 percent stated that reducing energy costs is a top priority, while only 40 percent said the same for decarbonisation.

As a technique with potential to cut both operational costs and carbon dioxide (CO2) emissions, energy efficiency has huge potential. This is particularly true for the efficiency of motor-driven systems.

More than 45 percent of all electricity produced today is consumed by industrial electric motors – and that is set to double by 2040. This transition will place greater demand on electricity resources, which is likely to keep prices high.

In this environment, energy efficiency is perhaps the best opportunity available for industrial businesses like pulp and paper mills that want to reduce their CO2 emissions in line with Net

Zero targets while also cutting operational expenditure (OPEX) by reducing energy demand.

By improving the efficiency of a mill’s electric motors and variable speed drives, an operator’s investment in energy efficiency can pay for itself – an effect that becomes stronger when energy prices are high.

However, the challenge is knowing where to target this investment. A typical pulp and paper mill might have a fleet of

Pulp Paper & Logistics ABB July/August 2023 10

hundreds of motors, each of which has a unique set of operating parameters and loading patterns.

Digital energy efficiency audits

Traditionally, operators have used energy audits to find these opportunities. During a traditional audit, an expert will visit to gather data manually before analysing it and providing recommendations that show the

return on investment of taking actions. These tend to be used to gain deep insight into the largest motors on the critical line.

New developments in technology are now overcoming this barrier. Today, it’s possible for a mill’s own operators to deploy digital data-gathering through connected motors and variable speed drives (VSDs). A service expert can review this data remotely without necessarily having to travel to site. With this digital approach, it’s possible to extend a digital energy efficiency appraisal to cover many more motors, potentially even entire fleets. It has a secondary benefit of reducing CO2 emissions related to travel.

Analysis of the data from an energy efficiency perspective can show which motors are operating far from their peak efficiency and – crucially – how much energy is wasted. The expert can then identify potential actions to resolve this, and the costs of these. For example, they might suggest adjusting operational parameters so that the motor only operates when it can do so efficiently. Alternatively, they could recommend adding a VSD

to a fixed speed motor. A further option is to modernise an entire electric drivetrain, made up of a motor and VSD, to premium efficiency technology and sending the time-served system to be recycled.

Similar data from connected motors can also be analysed to provide insight into motor condition, performance and health. Plant managers can use this as the basis of a conditionbased maintenance strategy that minimises unplanned downtime by identifying and resolving issues before they happen.

Two pulp and paper mills in Sweden are at the forefront of the digital approach and are using digital energy audits to reduce energy consumption and cut emissions.

Data-driven approach

enables SCA Group to target 50 GWh annual savings SCA Group’s kraft paper mill at Munksund in north east Sweden produces 400,000 tonnes of packaging per year and has a strong focus on sustainability. It uses bioenergy to generate most of its electricity and this has enabled it to become 95 percent fossil-fuel-free. However, its managers saw an opportunity to save more energy by targeting the 2,400 electric motors that drive its processes.

Anders Kyösti, the site’s technical manager, said: “Our objective is to improve energy efficiency through enhancements of at least 50 GWh per year based on the company’s energy consumption in 2020. Electrical motors account for a large part of our electricity consumption. Given higher energy prices and the trend towards electrification, optimising energy use will become even more important in the future.”

Motor data is gathered and uploaded directly to the cloud, where it is accessed at regular intervals by an ABB energy efficiency experts. They evaluate the energy consumed by individual motors and compare it with the work done. The experts provide a regular report with recommendations on actions, as well as their cost and the return on investment that can be achieved.

This provides evidence for SCA to prioritise investments in upgrading motors, adding VSDs or changing the operating regime to save energy. The advantage of carrying out this review periodically is that as the cost of energy changes, so does the payback period. Therefore, when energy prices are high, the operator can achieve savings by acting quickly.

SCA’s team is also looking at data from the same source to understand and improve the reliability and availability of its machines under a conditionmonitoring strategy. This enables it to carry out predictive maintenance and optimise its operations.

A further benefit of monitoring and evaluating energy efficiency is the sustainable recycling of motors that have been replaced by modern high-efficiency models. By separating old motors into their component materials, ABB’s recycling partner in the Nordics, Stena Recycling, can recover high-value copper and iron. This can then be recycled for use in new products in a circular process that reduces CO2 emissions and water compared with using virgin materials.

a mill that is identifying energy efficiency savings as a secondary benefit to using condition monitoring. The mill produces 190,000 tonnes of bleached chemi-thermo-mechanical pulp (BCTMP) per year for production of paperboard, tissue, printing paper and writing paper using wood chips from its parent company ATA Group, a major producer of sawn timber. Its mill is one of the most modern and efficient BCTMP mills in the world. To build on this, Waggeryd decided to connect its motors to the cloud with the goal of gaining continuous insight and deep knowledge about the equipment serving its critical line. To achieve this, it is gathering data from around 100 critical motors out of a total installed base of 450 motors.

As well as providing insight into the performance and condition of motors to support Waggeryd’s maintenance planning, the data has also identified energy-saving opportunities. An initial report in

early 2022 identified 10 motors with low operating efficiency, as well as others that are oversized (and therefore underutilised).

Using this insight, Waggeryd decided to prioritise upgrade of six of these motors. This shows how the data-driven approach can be

used to pinpoint energy savings that could be hard to identify in other ways.

Andreas Råvik, mill manager at Waggeryd Cell, said: “We have improved our energy efficiency by working with ABB. By using their energy reports, we can identify

assets like incorrectly dimensioned motors, or old motors with poor efficiency, and replace them.”

Data-driven decisions

Although some of its early adopters come from the Nordic pulp and paper industries, this new breed of digital powertrain service can be applied to any industry, anywhere.

It is a potential solution to operators that are under pressure to make the best possible use of energy resources. Digital energy efficiency audits, which are sometimes also known as appraisals, can help by pinpointing the precise location of potential energy savings in mills and other sites.

Ultimately, as a new-generation service that sits alongside remote condition monitoring, digital energy audit services can help pulp and paper mills to cut energy consumption and target investment where they can get the most benefit.

Flow control options in an evolving industry

The range of valves that offer flow control options for the pulp, paper, board and tissue industry is immense.

and paper industry management at Valmet’s

line, delves into the details of its scope

Valves play a vital part in pulp, paper, board and tissue production. As efficiency, reliability, sustainability, safety and profitability demands on processes have grown over time, the valve technologies have also developed immensely. Valmet is an active participant in driving modern flow control solutions forward to best serve its customers.

The role of valves as a part of the process is important in many ways. While accurate flow control has a direct impact on the quality of the end products, perhaps more importantly the right valve selection can significantly help improve the

efficiency and sustainability of the process itself. This of course also means creating savings and lowering overall costs. Valves, especially when paired with intelligent control and increased levels of automation, can make a real difference.

Valmet today is in a unique position after the addition of flow control solutions to its overall offering. With the industry’s strongest valve portfolio complementing Valmet’s process technology, advanced automation and expert service offering, we can truly provide customers with added value that far surpasses what any other supplier can offer today – all from one reliable source.

director

History of industry leadership

Valves may not be thought of as central components of the process, but there are literally thousands of valves involved in the journey from wood to pulp to finished end product.

Today, still more than 75 percent of the world’s pulp passes through at least one of our valves during production. More than 60 years in the service of the pulp and paper industries may also have a lot to do with it. Also, our offering of world-renowned valve solutions from trademarked product brands such as Neles, Jamesbury, Neles Easyflow, Stonel, Valvcon and Flowrox enjoys a strong reputation of quality, accuracy, safety and reliability.

We have always taken pride in our position as an industry trailblazer when it comes to valve technologies used in the pulp, paper, board and tissue processes. Our flow control portfolio consists of all the typical valves for control and on-off use, including ball, butterfly and segment valves. Additionally, our industry-leading offering also includes a wide range of accessories, intelligent devices and software products, all engineered to meet each individual pulp or paper mill’s needs and challenges.

Innovation has always been a key driver for product development. There are many pulp and paper-

specific flow control products in use today, that have their origins on our desks. Such innovations over the years have included the capping valve for batch cooking, a high-consistency valve for bleaching, a valve for basis weight control, ceramic ball valves for erosive applications as well as a host of intelligent valve controllers, to name a few.

Meeting modern industry demands

Every day, I see first-hand how our industry-leading valve solutions are helping improve business performance in mills around the world. Our solutions are helping customers maximise process efficiency, availability and performance, all while improving the safety and reliability across the lifecycle of the entire mill.

The rising cost and growing scarcity of both raw materials and energy will continue to drive the need for improving process performance and efficiency in the future. Also, we have seen that despite what many thought, the pulp, paper, board and tissue

segment has grown steadily, and will continue to grow.

The reduction in demand for printing and writing paper in this digital era has not stopped the growth in demand for other pulp-based products. If anything, this more environmentallyconscious society we live in has driven the demand for non-plastic alternatives for many traditional products from packaging materials to drinking straws. We are even seeing the emergence of new pulp-based textile fibres.

A versatile offering is key

So, while the basic functions of valves in different parts of the papermaking process may have stayed largely unchanged over time, the growing demands related to efficiency, profitability, safety, reliability and sustainability have been active drivers for product development and R&D. Our improved globe valve

continues to deliver excellent control performance in highpressure applications such as boilers in operation at mill power plants. At the same time, our latest versatile butterfly valves are proving to be an optimum solution for a host of end uses thanks to their modular yet robust and reliable design and construction.

The continuing developments in digitalisation, automation and networking of smart devices have been one of the biggest gamechangers in industry as a whole. This is also true in the pulp, paper,

board and tissue industries. The virtually real-time control and monitoring capabilities that come with smart devices such as our NDX valve controllers are the modern way to ensure process quality and performance. With seamless connectivity and compatibility with Valmet’s vast automation offering, the customer benefits are further amplified.

Service keeps getting smarter

Predictive maintenance is the best way to avoid problems and ensure reliability and optimised process uptime. It is made possible by accurate real time data used to fine tune a predictive maintenance plan based on decades of application knowledge, service experience and statistical analysis of service records. The latest development in further integrating intelligence to improve service planning, the Valmet Industrial Internet (VII), will be made available to the first customers this year.

It’s about much more than just data on current valve performance. It incorporates our vast installed base data, decades of service experience, diagnostics, device service history and current performance. So basically, everything you need to plan service and maintenance operations on a device and mill level.

I also emphasis that the ability

to harness our long-running pulp and paper industry experience and understanding to ensure the best available services anywhere in the world, puts Valmet in a strong position. We combine the latest technologies with the strongest industry experience to provide our customers a level of service that gives them a measurable competitive edge in business.

A continued commitment to the industry

Valmet’s state-of-the-art valve production facilities around the world, and our convenientlyplaced service centres, ensure that we can provide the best in both products and services to customers worldwide. Flow control solutions and a wide range of lifecycle services are provided for both greenfield projects and the many conversion projects from paper to board production.

Our Flow Control Business Line is partnered with existing mills all across the globe. At the same time, we are happy to see so many new mill projects starting up – not just across Northern and Central Europe, but also in the Americas and across China and Asia Pacific.

Just this year, we delivered more than 3,000 individual valves to Metsä Group’s new bioproduct mill project in Kemi, Finland. To help collect performance data and optimise future valve service and maintenance operations a majority of the delivered valves were fitted with our intelligent valve controllers.

We are thrilled about being a part of projects like this. With the continued demand for pulp, the shift from paper to board and tissue and the emergence of new innovative pulp-based products, this is an exciting industry that we want to be a part of developing and serving.

Electric storm

As tissue mills try to optimise their energy consumption with sustainability as a priority, the launch by Andritz of a hood air heating system using electrical energy is very timely.

From environmental considerations to the basic economics of running any energyintensive process, there are today many reasons for tissue mills to examine their energy strategy. Add in the uncertainty over gas supply created by the current geopolitical situation and the case for electricity becomes very compelling.

This is particularly the case in

any location where wind and sun are in plentiful supply. There is a growing list of mills which source electrical energy, at least in part, from renewables. In Europe and the USA, there is tax to pay on emissions, including carbon dioxide, which provides a further incentive to use electricallypowered systems, particularly if the power is sourced from renewables rather than fossil fuels. Government subsidies on

renewable energy are another factor in the equation.

In this context, Andritz has taken a wealth of knowledge regarding electrical heating, in the drying of spunbond materials for nonwovens in some of their installations and applied it to hood air systems for tissue machines. The result is the PrimeDry Hood E, which uses the same air system as gas- or steam-heated hoods, but with electric heaters replacing

offering flexibility in operation

gas burners or steam heaters. The result is a system capable of achieving air temperatures of between 400 and 450 deg C.

Energy efficiency boost

Compared with, for instance, gas-heated systems, PrimeDry Hood E increases energy efficiency for the hood drying system by up to 4 percent. Electrical heating is more efficient because a conventional gas burner requires

Pulp Paper & Logistics ANDRITZ July/August 2023 16
The Andritz PrimeDry Hood E uses electrical heating for the dryers in tissue mills, reducing emissions and

heating of both the combustion air and drying air for the burner to function, while electrical heating does not require combustion air. And in theory at least, 100 percent of electrical energy is converted into thermal energy. Compared to steam-heated systems, the PrimeDry Hood E can increase production through its capability to achieve elevated temperatures.

Electrical heating offers the further advantage that no combustion residuals are emitted to the air. Overall, tissue

machines can expect a reduction in carbon dioxide emissions of approximately 70 percent compared to a conventional gas-heated system. In many parts of the world, Europe and the USA included, mills pay tax on emissions to the atmosphere, so there is a clear economic argument for electric heating as well.

The potential for lower availability compared with gasheated air systems is mitigated by the use of filters with automatic cleaning in case of low temperatures, as is already implemented with steam-heated hoods.

There are two types of electric heaters available from Andritz: the Corner Type and the In-Line Type. In performance there is no difference, but each format is suited for a particular mill layout and recommended on a caseby-case basis. Electrical heating comprises the main body of the electrical resistor, a terminal box and control panel, the placement of which is flexible.

While the application of electric heating for hood air in tissue production is new, electrical heating in industrial contexts where drying is involved is not.

So, it has the benefits of being proven technology – for instance in some Andritz nonwovens installations. It also means that there are existing design solutions to manage specific situations, such as where there is the potential for seismic activity.

The electrical heater has been specifically designed with least disruptive maintenance in mind. The standard system enables easy removal of both top/bottom and laterally affixed resistors by unbolting them from the plates. Andritz proposes an even more convenient solution, in which the heating elements can be removed in bundles from the duct heater rather than having to extract the whole duct heater installation. Through a minor modification of the duct heater design, this refinement facilitates maintenance of a single heating bundle while the tissue machine continues to operate at a lower capacity, rather than being shut down completely.

A positive addition in a changing world

Electrical heating is a positive addition to Andritz ’s portfolio in a changing world. It is not

going to suit every situation, but its flexibility makes it widely applicable. Renewable energy sources might not be available 24/7, but a hybrid system which can switch between gas and electric heating for hood air enables a mill to switch the fuel source, which is most suitable for prevailing climatic conditions, time of day, or even changing tariffs for gas and electricity over a 24-hour period. It is a question both of optimising energy cost and security. And if drying capacity is a limiting factor in any tissuemaking scenario, the addition of electrical heating can increase capacity.

As a new application of a tried and tested technology, there is minimal technical risk to the user. PrimeDry Hood E is equally suitable for dry-crepe tissue production as for textured or structured (TAD) tissue machines. With zero carbon dioxide emissions from combustion, there is also a benefit to the final product’s eco credentials. This will appeal to the consumer and therefore the retailer. A genuine marketing opportunity born out of technology – and based on hot air.

Increase lifetime and improve runnability with the correct felt conditioning

How should the showers be set up?

Generally speaking, conditioning starts with a high pressure shower. If necessary, this is followed by an edge shower. This should then be followed by a low pressure shower and a Uhle box. This order should be strictly adhered to. With this setup, the felt surface is adequately lubricated before coming into contact with the aggressive ceramic coatings of the Uhle box covers. All these elements generally interact with the paper side of the felt.

High-pressure shower for deep cleaning

Dirt, fines and fillers are introduced into the process through the paper stock, which can subsequently lead to compaction of the felt. This can result in diminished dewatering over the lifetime of the felt. Numerous settings must be taken into account to ensure that mechanical felt cleaning is effective. The more precisely this is carried out, the more efficient the felt performance.

Cleaning must be continuous and even

The basic objective is the removal of dirt and deposits from the

inside of the felt in a continuous and balanced manner. This needs to be done over the entire length and width of the clothing. It is important to ensure that every square centimetre of the felt is cleaned equally well. If this is not done, it is likely that there will be different levels of contamination and, therefore, different levels of felt compaction. This can then lead to cross-profile variations in the felt and paper, or can incur locally increased wear. And, last but by no means least, to premature removals.

The needle jet

There are several key factors in the correct operation of a highpressure shower pipe. Two of them are particularly important to pay attention to:

l The high-pressure needle jet must always be laminar. This is the only way to ensure that the full energy of the jet reaches the felt surface. A turbulent jet that is inclined to break up before reaching the felt will lose energy and therefore be unable to apply its full cleaning power (the differences are shown in Figures 1a and 1b).

l Heimbach also recommends that a distance of 100mm from the shower nozzle outlet to

the felt surface is respected. Heimbach has had good experiences when the needle jet works at a 90-degree angle to the press felt.

The nozzles

All nozzles need to be in perfect condition to ensure that the felt is evenly cleaned across its full width. They must not be either polluted or clogged (see Figure 2). Unfortunately, this is often not the case in practice. Accordingly, felts are frequently encountered in the most varied degrees of contamination (See Figure 3). The distance between individual nozzles should ideally be between 100 and 150mm. The exact distance depends on the required cleaning intensity in the respective felt position. This leads on to another important aspect of felt conditioning: the correct oscillation of the highpressure shower pipe. In order to reach every single point of the felt with a thin needle jet,

Pulp Paper & Logistics HEIMBACH July/August 2023 18
Felt conditioning plays a key role in the increased production efficiency. Clothing expert Heimbach often notices that this issue does not always receive the attention that it deserves. PPL reports
Figure 1a - laminar jet Figure 1b - Turbulent jet

the high-pressure shower must constantly traverse across the width. For the most homogenous deep clean to be effective, a single or multiple of the nozzle spacing should be selected as the stroke.

As for nozzle quality, two further questions arise: What should be the optimum diameter? How high should the pressure applied reach? For some years now, the trend has been towards smaller-diameter nozzles. They certainly offer better cleaning – provided they do not become prematurely clogged due to poor water quality. Diameters between 0.7 and 0.9mm are common today.

Water quality

Central to the service life of the shower nozzles is the quality of water in use. Heimbach advises fresh water or alternatively superclear filtrate. The aim is always to keep the amount of suspended particles introduced into the system in the water as low as possible. Otherwise, there is a risk that nozzles can become clogged or nozzle filters polluted.

As much as necessary, but as little as possible

The higher the pressure, the more the stress on the felt surface. Of course, finer fibres will have less resistance than coarser ones. Overall, the felt should be treated

under moderate pressure (up to 10 bar) over the first few days with the intensity then increased over clothing lifetime. For continuous HP cleaning, 25 bar should be regarded as the upper limit. For short periods, around 30 bar can be acceptable.

Ultra-high pressure showers for even better felt life

The specifications as outlined should not, however, be set in stone. This is because newlydeveloped ultra-high pressure shower systems now promise new opportunities. We have seen numerous positive results on packaging grades when using units with a nozzle diameter of 0.25mm

and a pressure of 50 to 160 bar. This has not led to any noticeable decrease in felt wear, but has provided positive results in terms of cleaning – and fresh water consumption.

Low-pressure showers for lubrication

With its fan nozzles, a lowpressure shower will introduce large quantities of water to the felt. This keeps the felt moisturised throughout and provides a potent lubricating effect before the Uhle box.

Uniform water application

For ideal low-pressure spray shower operation, we recommend

Pulp Paper & Logistics HEIMBACH July/August 2023 19
Figure 2 - Functioning and clogged nozzles Figure 4 - Uneven water application due to disturbed fan jet Figure 3 - Irregular cross direction profile due to misplaced HP nozzles Figure 5 - Uneven water application

that the following parameters are respected: Water should be applied from all fan nozzles with a slightly overlapping jet at a distance of 100 up to 150 mm maximum from the felt surface and at a slightly inclined angle to the direction of felt travel. If water is applied unevenly (See Figures 4 and 5), trouble can develop quite rapidly. Firstly, moisture fluctuations will occur in the felt, which will be reflected in damp and dry areas (See Figure 6). The irregularities can be quickly picked up by measuring water content, or in many cases can be seen by the naked eye.

Wet/dry streaks such as these in the felt rapidly transfer to the sheet, leading to irregular cross direction moisture profiles.

Slightly overlapping fan jet

The graphic (shown in Figure 7) illustrates the importance of an overlap of fan jets. Either no

overlap, or too much, will cause irregularities in cross machine profiles.

Dry streaks can, in some cases,

lead directly to increased felt wear (as shown in Figures 8 and 9). This is due to a lack of lubrication and the resulting increased friction over the Uhle box cover. This then can be a cause of premature felt removal. Unlike the highpressure shower, the low-pressure version does not oscillate. Clear filtrate water is generally used to pressurise the fan nozzles with water.

Uhle boxes for dewatering

Uhle boxes have the added task of indirectly dewatering the sheet by means of the press felts. Using vacuum, some of the water transported in the clothing is sucked away by the units. This means high stress for the felt, as it is in permanent contact with the Uhle box due to the set vacuum. It should also be noted that this happens at speeds up to 2,000 metres per minute. In this case, contact also means friction, which not infrequently leads to loss of batt from the felt.

Correct adjustment of the edge deckles

With the Uhle box, there is always a risk of adjustment errors which could cause the

Pulp Paper & Logistics HEIMBACH July/August 2023 20
Figure 7 – Showing effect of overlapping fan jets, or lack of it Figure 6 – Wet streaks in felt

press felt to suffer premature wear, causing early removal from the paper machine.

In one case, a felt suffered premature removal, as the whole of the fibre batt had been removed in the edge area (shown in Figure 10). This was due to incorrect setting and positioning of the edge deckles (shown in Figure 11).

These should ideally be aligned with the plastic or ceramic blades of the Uhle box. Otherwise, the felt rubs permanently against the edge of the raised deckles and as a result continuously wears away the fibre batt.

Special care with seam felts

Heimbach often observes that edge deckles are not optimally set. Just as with the low-pressure shower units, a deficiency like this can lead to uneven moisture – this time in the sensitive edge area of the press felt (see Figure 12). This can become very critical where seam felts are concerned: Such fluctuations put a lot of stress on the MD yarns and seam loops. As a result there will be risk of seam opening.

Correct vacuum settings

There is no rule of thumb for the correct vacuum in a Uhle box. It can be stated, however, that

higher vacuums generally lead to higher felt wear. This is one of the main reasons why Heimbach clearly favours nip dewatering at medium and high speeds. In these cases, it is possible to run with a substantially reduced vacuum or even to completely dispense with Uhle boxes. This

reduces felt wear but also saves energy.

Replace worn, sharp-edged covers

It is important to ensure that nothing is deposited on the Uhle box cover that could lead to melt marks in the press felt. Worn or sharp edged covers must be replaced as they can have a negative impact on felt service life.

Slotted or drilled Uhle box covers?

Slotted covers remain the standard here. It is however true that drilled covers have become more popular. The clothing expert Heimbach certainly sees the benefits of this cover design type: be it through reduced felt wear or improved profiles of felt and sheet.

Replacing refractory with safety and efficiency

Lime kilns play a vital role in pulp and paper mills as they convert calcium carbonate (a by-product of the pulping process) to calcium oxide (lime). The lime returns back to the pulping process, completing the loop used by mills in the Kraft-pulping process.

The mills rely on functioning, quality refractory to keep the plant up and running. The worst nightmare for these operations is unplanned downtime and maintenance. One shutdown can cost mills thousands of dollars a day in lost production, especially for a facility that is producing more than 300,000 tons of pulp and paper per year.

One mill in Terrace Bay, Ontario, faced a refractory failure just one year after a fresh installation. The mill had an assessment completed which identified the problem as poor installation and inferior bricks.

To combat this, the pulp and paper mill reached out to a man known for his quality bricking installations: John Taylor, founder and president of Kingston Refractory Services (KRS). Taylor and his team knew they needed to do the job right. And the best way to do that is to use the most effective equipment, which is why they rented, and ultimately

purchased, a bricking machine from Bricking Solutions.

Contracting excellence

When looking for a new contractor to install refractory brick, the pulp and paper mill’s

management knew it needed someone who’s been in the business for a long time with a reputation for quality work. Taylor was just the man. He worked as a brick layer with the brick layer’s union out of Kingston before

starting his own company. When he had the opportunity to do a refractory brick installation for a large cement facility in 2008, he and his wife, Laurie, worked together to start their own company: Kingston Refractory Services (KRS).

KRS provides refractory engineering, demolition, installation, clean up, anchor removal and more. They primarily service the southern Ontario region of Canada with a few customers in northern Ontario. Most of the facilities they work with own their own custom bricking machines for refractory installation. This is where Taylor and his team were first introduced to Bricking Solutions, which left an impression on a man who is known for his commitment to his team’s safety.

Andrew Wojciechowski, director of operations for Kingston Refractory Service’s subsidiary branch, Réfractaire Québec, explained, “John is adamant about safety in the field. It is the number-one priority for us and always has been. KRS is going on six years without any kind of safety-related incident. We’ve even stopped working before when an installation became unsafe just to reassess our methods.”

Taylor found that bricking machines provided the safest and highest-performing installations

Pulp Paper & Logistics
July/August 2023 22
BRICKING SOLUTIONS
When the refractory in kilns used in pulp and paper mills needs to be replaced, bricking machines provided the safest and highest-performing option, explains Heather Harding*
The Kingston Refractory crew is able to install the bricking machine in just 60 to 90 minutes, whereas other methods take between six to eight hours to set up

in the business. For the first installation with the pulp and paper mill, he decided to rent a Bricking Solutions EZ Flexx50 bricking machine.

The safest choice

The first step of the pulp and paper mill installation came in a single kiln rebricking. Taylor and his crew decided to rent a bricking machine for the process. The EZ Flexx50 bricking machine is capable of bricking 9.8- to 13-foot (3-to-4m) interior diameter kilns and has a 6,600-pound (3,000 kg) load capacity with a 12-foot (3.65m) work platform. Made of 6061-T6 aircraft-grade aluminium, the structure is as strong as steel but weighs two-thirds less. Their crew can install the bricking machine in just 60 to 90 minutes whereas other methods take between six to eight hours to set up.

The previous installation used the pogo stick method, one of the oldest systems for bricking installation. This method suites all brick shapes but, unfortunately, setup time can take as long as a day in larger kilns. It uses a fabricated wooden arch that sits on a platform and uses spring loaded rods – pogo sticks – to push the bricks against the kiln shell to hold them in place. This approach limits installers to just one course at a time to ensure the jig doesn’t collapse. Because one pogo stick is required for each brick, and must be individually set and retracted, installation time is extended. There also isn’t a standard platform available to facilitate the bricking procedure and no international design or safety standards. This installation method is also very hard on the bodies of the crew because it requires a lot of above-height work. Workers

are required to set up each individual pogo stick and hold the bricking in place as they go, risking worker fatigue. A group of skilled workers using a bricking machine can complete a project twice as quickly as they could with another method. The pneumatic ring of the bricking machine holds the bricks against the shell of the kiln instead of relying on crew members to do so manually. The most challenging feature of the kiln in the pulp and paper mill came in the dual layer installation. This type of installation requires two layers of brick, first a layer of insulation brick mortared together and, second, a layer of hot face brick. The bricking machine

significantly improved the efficiency of the installation team because the arch could easily be adjusted to fit the second ring of brick instead of requiring a change of pogo sticks that the previous method required. The bricking machine’s arches hold each brick firmly against the kiln shell to reduce the risk of sagging. This properly aligns the brickwork and fights against catastrophic failure, which is what the pulp and paper mill experienced with the last installation.

“Both the plant and our team were extremely satisfied with the result of the project with the use of the Bricking Solutions bricking machine,” Wojciechowski

said. “Being able to use the bricking machine for the plant allowed the customer to see the technology and experience the results in real-time.”

Partners for the long term

The increased efficiency of the bricking machine alongside the extended lifespan of the refractory brick impressed the pulp and paper mill’s management so much that they invited KRS back to do a full shutdown at the facility. To complete the shutdown, KRS decided to purchase an EZ Flexx50 bricking machine of their own. It gave them the opportunity to complete the rebricking of the kiln and offer more options to clients who may not own their own machine.

John Taylor and the KRS team always want to build a partnership with their clients for the long-term. The full rebricking job was completed ahead of time and under budget with the use of the newly-purchased Bricking Solutions bricking machine.

The mill was extremely satisfied with the results of the installation and the quality of the refractory brick lining, especially when they found that the refractory lifespan was stretched to an impressive three years. The pulp and paper mill reached out to KRS to work with them for the next refractory installation project that they’ll be completing soon.

Updated L&W bursting strength tester launched Maintenance of automation software improved by ABB

The latest version of ABB’s Automation Software Maintenance (ASM) lifecycle management program has been launched to cover the software related to Paper Machine Drives (PMC800) and Pulp and Paper Process Control Library (PPLib800xA).

It is an extension of ABB’s ASM program, and complements the Quality Control System (QCS) that was introduced in January 2023.

The basis of all ASM programs is to offer a tiered subscription service that enables system evolution from older versions to the latest and/or provide on-demand access to regular software updates that include incremental improvements, patches and new features.

This proactive system management helps pulp, paper,

packaging and tissue mills to maximise their system investment and reduce maintenance and support costs.

ASM tiered subscription options open up the features available as mills go through the upgrade process. Maintain Plus provides customers with access to incremental updates for PPLib800xA and PM Drives containing fixes and enhancements, meaning mill operators can benefit from new or improved features, as well as keep pace with important cyber security updates. Maintain & Evolve includes all the benefits of the Maintain Plus level, with the added ability to upgrade from an older legacy system version to the latest and between system generations.

The program also gives users of both PPLib800xA and PM Drives access to the myABB business portal for program management and premium system documentation, helping keep process control software up to date.

With PM Drives ASM, mill operators can benefit from free licenses to ABB’s newest drives software applications such as Datalogger and PM Drives Performance – allowing them to leverage data for more predictive maintenance and troubleshooting –as well as machine control safety.

With PPLib800xA ASM, the subscription enables an improved human-machine interface (HMI) experience and access to the PPSupport tool, a .Net stand-alone application that detects unintended

System (LMS), which provides connectivity to the full Quality Data Management and Manufacturing Execution System (MES), enabling greater visibility of quality data across the mill and enterprise.

“Pulp and paper mill customers that transition to ABB’s newgeneration L&W Bursting Strength Tester can look forward to the same long lifecycle as other instruments from the L&W product portfolio as well as the benefits with the new technology and digital possibilities,” says Ghazal Amar, global product manager for paper testing equipment at ABB. “Connectivity to digital lab management systems like ABB’s L&W LMS automates reporting and enables mills to do more in less time.”

changes and aids system engineers in migrating the existing process application libraries to the latest version.

“ABB’s ASM lifecycle management program has been expanded to offer proactive mill operators even better support for their pulp and paper-specific software, allowing them to better manage and predict total cost of ownership,” said Shankar Singh, global product line manager for drives and automationin ABB‘s pulp and paper business.

“Customers can unlock new features for improved troubleshooting and advanced performance, while at the same time keeping their system software up to date.”

SCA improves efficiency and saves resources at Obbola mill

In Sweden, SCA reports that it is successfully using Voith’s digital and automation systems to optimise the production efficiency of the new XcelLine paper machine at its Obbola mill.

The PM2 line, said to be the world’s largest of its type annually producing 725,000 tons of kraftliner with basis weights between 100 and 200 gsm, was commissioned by the full-line supplier last year. It has a wire width of 10.2 metres and a design speed of up to 1,400 metres per minute.

“The journey for SCA and Voith together has only just begun,” says Gustaf Nygren, manager of the Obbola mill. “We have a long-term partnership in place with the target of reaching the common vision of PM2 in Obbola becoming the new reference for safety, efficiency and digitalisation.”

To achieve its goals, SCA is using more than 10 innovative digitalisation and automation systems throughout the machine, all from Voith’s Papermaking 4.0 portfolio, and its BTG subsidiary.

Typically, the OnEfficiency family helps increase line efficiency and stabilise product and process quality. The improved efficiency reportedly also contributes to more sustainable and resourcesaving paper production. SCA uses applications from the OnCare family to monitor productivity and to quickly take optimisation measures.

Machine availability is further increased by digital services such as the OnCall.Video remote maintenance service. The digital

portfolio is made available on Voith’s IIoT dataPARC cloud platform, which features the highest security standards.

“With the PM2, we will take our next steps in the digitalisation journey. The applications provided by Voith will help us to monitor the process and make the right decisions,” says Niclas Ahnmark, paper mill manager at SCA.

SCA has also signed a longterm service agreement with Voith subsidiary BTG for process control. BTG’s Lifecycle programme

ensures optimum consistency and control with the use of preventive maintenance for all of the consistency sensors, including regular calibration and routine checks. BTG Field Service Engineers assist in the planning, implementation and coordination of the various maintenance services, maximising machine uptime and stability while maintaining SCA’s high safety standards.

The collaboration with SCA is long-term and is particularly evident through the Efficiency Partnership. Throughout the process, the teams work closely together to ensure that the systems are used at the optimum.

Stephan Sicking, vice president of sales for the EMEA region at Voith Paper, explains: “As part of a digitalisation roadmap, we have defined common goals and KPIs in a cross-functional team, developed a customised concept and are now providing support for successive installation and employee training. Already, the benefits from this collaborative approach are clearly demonstrated.”
