Centrifugal Fans Named After Industrial Process

Centrifugal Fans Named After Industrial Process

Neel Rao Writes on Industrial Centrifugal Fans & Centrifugal blowers technologies for Reitz India

Depending on the industrial requirements of airflow rate, volume, and pressure centrifugal fans have been customised to serve industry.

Centrifugal fans are named as per the function served by them. They are often referred with different names based on the industrial process they support. While the technical functionality of these fans is same, the design element is changed to support several industrial processes.

Combustion Air Fans A good air delivery system is required for the burner system. These fans are designed to give pulse free airflow with constant pressure. The amount of airflow can be controlled by using louvers, inlet guide vanes and variable speed drives, thus improving the boilers efficiency.

Dedusting Fans Centrifugal fans find its diverse market in the dedusting application. The system works as a pressure type system where dust particles move through the fan.

Raw Mill Fans A raw mill is an equipment used to grind raw materials into raw mix during the manufacturing of cement. Raw mill fan finds its application in cement industry. It carries gas and raw particles. It is possible to obtain very low pressure drop with the help of Raw mill fan. Its operation is behind cyclone.

Impeller and main disc are equipped with wear protection. It can provide volume flow of 80-350 m3/s at a temperature of 90-100o C.

Raw Mill Baghouse Fans It also finds its application in cement industry. It can provide volume flow of 100-400 m3/s. It often comes with aerofoiled blades. In most of the cases the fan control is provided by variable frequency drives.

Coal Mill Fans Proper burning of coal in cement industry require proper air supply .

Exhaust air should also be removed efficiently. These fans help in good combustion of coal in the cement industry.

Cooling Fans The clinker in the cement industry has to be cooled from 1500oC to 100oC. Cooling the kiln protects the equipments and help maintaining proper

minerals in clinker so that good quality of clinker is maintained. Cooling fans also help manage power consumption.

Flue Gas Recirculaion Fans Thermal combustion process releases gases which contain lots of flue gas pollution content. Flue gas recirculation fans reduce flue gas pollution content. Nitrogen oxide is also a major pollutant released during thermal combustion. Flue gas is recirculated into the combustion chamber to reduce nitrogen oxide emission.

Primary Air Fans Primary air fans serve the purpose of supplying fuel to the furnace so that combustion takes place properly. Backward curved centrifugal fans are

commonly used as Primary Air fans. They find their applications in cement industry, power plant industry etc.

About REITZINDIA Reitz India has set a benchmark to deliver high quality fans for heavy duty industries which can work at precise operating conditions like high temperatures and pressures. Reitz offer idealistic Centrifugal Fan and Centrifugal blower design that can be used in all large scale process industries like cement, iron & steel, power plants, fertilizers/ chemicals and more.
