Large savings
November 1st 2007 A million pounds in energy savings is expected following installation of ABB drives at Corus Strip Products in Port Talbot, South Wales. As part of a plant-wide energysaving programme, 24 ABB industrial drives, ranging from 140 to 400kW, are being installed to control pumps on the hot strip and cold mills, plus three fans on the coke ovens. The pumps recirculate cooling water in the mills, while the fans are used for dust extraction at the coke ovens. The applications have varying demand but, until recently, pumps and fans were running continuously at full speed. Running to demand will not only reduce energy costs but save water and improve control, particularly of the cold mill which could result in better product quality. ABB says low voltage drives are used as they have a smaller footprint than medium voltage versions. A transformer reduces the voltage from the 3.3kV network on the site to the 690V used by the drives. More articles from ABB Ltd (Drives & Motors): |
