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。

Abstract

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

results show that the oxygen quantity maintained at about 3.0 in operation

the revolution speed of classifier of coal pulverizer at 30~35 r/min

the fired-off air rate at about 25%

and the secondary air gate at a suitable open degree

the economic efficiency of boiler combustion can be enhanced to a good level.
