TURBO GENERATOR PACKAGES FOR BIOMASS THERMOPOWER PLANTS WEG IS SUPPLYING OXE ENERGIA WITH FOUR COMPLETE sets of turbo generators – including logistics, assembly and commissioning services – for use in four biomass thermopower plants located in the northern state of Roraima in Brazil. The contract includes the installation of four reaction and condensation turbines, with two CT model back-side installation uncontrolled outlets, together with four 12.5MVA, 13.8kV, 1,800rpm, 60Hz three-phase synchronous generators, plus the protection and monitoring electrical panels. Due to be installed in two different locations, the power plants will each have an individual installed generating capacity of 11.5MW and will use reforested wood chips as biomass. Delivery of the equipment was set to take place in the
first quarter of 2021, with the forecast for the operation and commercialisation of energy by June. weg.net
COMPRESSOR MOTOR RUSH JOB SECURES OXYGEN SUPPLY WORKING UNDER HIGH PRESSURE, Menzel Elektromotoren was able to complete two much-needed compressor motors and deliver them in just two weeks at the turn of the year. An order, which came from Bangladesh, was to ensure the supply of medical oxygen, which had an added urgency during the current pandemic. A Spanish gas manufacturer needed to replace a failed motor quickly to minimise production downtime and revenue loss. Menzel was able to provide highvoltage motors with outputs of 3000kW and 5200kW and coolers from stock. All the necessary interface modifications were carried out in-house in the short time available, including the conversion from air-to-air to air-towater cooling, machining the shaft end, installing a support and flange for an oil pump, converting the terminal boxes, and boring new foot holes.
Special technical expertise was required to secure the oxygen supply even in the event of grid fluctuations; Menzel’s technical department and the start-up transformer manufacturer
together calculated the ramp-up to ensure that the new motor was compatible with the existing starter. www.menzel-motors.com
