燃煤电站锅炉技改中控制氮氧化物的效果

The Principles and Effects of Nitrogen Oxide Control in Renovation of Coal-Fired Station

原锅炉热损失较大,NOx排放超标,改造后的锅炉增加了新型燃烧器,既减少了热损,又能减少NOx排放量,使NOx排放浓度达到国家规定标准。

Heat loss for original boiler is relatively large and NO, discharge exceeds the national standards. The renovated one is equipped with a new type of burning device with heat loss and NOx discharge reduced and NOx discharge concentration meets the national standards.
