摘　　要：选择2500 m^(3)高炉的卡鲁金顶燃式热风炉燃烧器为研究对象,开发设计助燃空气分级燃烧器以降低NO_(x)的排放。研究结果表明,空气分级燃烧器,先使高炉煤气在缺氧的环境中燃烧,燃烧后再通过下层的空气进一步燃烧,使燃烧室出口最高NO_(x)浓度由308.74 mg/m^(3)降到193.7 mg/m^(3),降低了37.26%。The kalugin’s hot air stove burner of 2 500 m^(3) blast furnace is the research object of this paper. The design of air-staged burner can reduce NO_(x) emissions. The results show that The air-staged burner, firstly make blast furnace gas combustion in the anoxic environment, then the unburned will burn through the lower air, the highest NO_(x) concentration is reduced to 193.7 mg/m^(3) from308.74 mg/m^(3) at the combustion chamber exit and about 37.26% is reduced.
