摘　　要：对神华国华绥中发电有限责任公司B厂3、4号机组锅炉一次风压、氧量、煤粉细度、二次风门、燃尽风率等进行了试验调整,结果表明锅炉运行氧量维持在3.0%左右,磨煤机分离器转数保持在30～50r/min,燃尽风率约为25%,以及保持合理的二次风门开度,可使锅炉燃烧经济性提高到良好的水平。The precise adjustment of primary air pressure,oxygen quantity, fineness of pulverized coal, secondary air gate,fired -off air rate,etc, for boilers of units no. 3 and no. 4 in B power plant subordinated to Suizhong Power Generation Co Ltd has been carried out, quantity maintained at about 3.0 in operation,the revolution speed of c -35 r/min,the firedoff air rate at about 25% ,and the secondary air the economic efficiency of boiler combustion can be enhanced to a good results show that the oxygen lassifier of coal pulverizer at 30 gate at a suitable open degree, level.
