Praxair, Inc.’s innovative Dilute Oxygen Combustion (DOC) technology contributed to ArcelorMittal receiving the 2010 Energy Achievement Award from the Association for Iron & Steel Technology. The award recognizes the steelmaker’s efforts to increase the energy efficiency of one of its reheat furnaces at its 84-inch hot strip mill in East Chicago, Ind. By utilizing the DOC technology with the installation of a 145 MMBtu/hour oxy-fuel system, the operation was able to reduce the fuel consumption by 0.26 million Btu per ton of steel (approximately 260,000 million Btu per year).

Praxair’s DOC technology is specifically designed to minimize installation costs and provide operational flexibility. It has been implemented successfully in more than 150 installations worldwide involving a variety of industries. According to ArcelorMittal, the reduction in natural gas from the single furnace conversion equates to the natural gas consumed by 1,945 homes for a year in the U.S. AIST presents this annual award to an individual or organization to recognize their deployment and use of innovative new technologies or practices that result in significant energy conservation improvements.
