摘　　要：针对钢铁企业的自备电厂全烧煤气锅炉降低二氧化硫排放浓度的问题,建立二氧化硫浓度在线预估模型,利用高炉煤气和转炉煤气协调控制,提前调整锅炉燃料配比,降低二氧化硫排放浓度的方法。通过生产实践证明了此方法的可行性。In order to reduce the flue emission concentration of sulfur dioxide of full gas boiler in the self-provided power plant of steel enterprise, an online evaluation model for SO2 concentration was established. Through coordinated control of blast furnace gas and converter gas, the fuel proportion of boiler was adjusted beforehand, to reduce the emission concentration of sulfur dioxide. The method has been proved practical through production.
