摘　　要：鞍钢新5号高炉2008年大修过程中,在热风炉系统采用了助燃空气、高炉煤气双预热技术。助燃空气预热是通过建2座卡普金式顶燃式预热炉来实现的,高炉煤气预热是通过在热风炉烟道上设置一台管式换热器回收烟气余热来实现的。这种双预热技术实现了在使用100%高炉煤气条件下达到风温1200℃的目标。In the rebuilding of blast furnace No. 5 in 2008, the combustion - supporting air and gas double preheat techniques were adopted in the hot blast stoves system. The combustion - supporting air preheat was realized by building two dome combustion. The Blast furnace gas preheat was achieved by installing the pipeline heat exchanger in the flue of hot blast stoves, and reclaiming the flue gas＇surplus heat. The double preheat techniques achieved the gas temperature to 1200℃.
