United States Steel - Irvin Plant, Dravosburg, PA

ALFA was hired by US Steel to supply necessary engineering and combustion services to optimize performance of five- (5) existing top and bottom fired recuperative pusher type slab reheating furnaces feeding an 80" hot mill. In addition, ALFA performed a thermal audit that was designed to validate the temperature set points and resultant fuel to air ratio flows that were controlled through an existing supervisory control system. Team efforts resulted in reduced energy consumption, reduced yield loss (less scale formation in furnaces), improved slab heating quality (consistent nominal discharge temperatures furnace to furnace) and slab temperature uniformity (top to bottom and lead to lag end).
