Ultralow-NOx Flat Flame Burner Application for Steel Reheat Furnaces

摘要

Steel producers worldwide face the competing challenges of reducing fuel consumption and meeting increasingly stringent emissions regulations when reheating steel. While central heat recuperators are a common means to reduce fuel consumption, conventional burner designs used on steel reheat furnaces yield higher nitrogen oxide (NOx) emissions through the higher resultant flame temperatures. As for newer, low-NOx burners, the choices are often limited by the design requirements of the furnace. Hauck Manufacturing Co. recently supplied a unique application of two different burners as a solution to these two competing challenges through the utilization of both side- and roof-fired ultralow-NOx burners for two advanced technology pusher steel reheat furnaces rated at 120 tons/hr, each designed by CMI Thermline in Belgium.
