摘要
电厂燃煤中掺烧一定比例的煤泥或煤的水分较大时,经常会发生堵煤现象,磨煤机因断煤而被迫停运。分析了堵煤原因后,为煤仓加装了空气炮及旋转清堵机,改善了煤仓的运行状况,并提出了清堵装置的季节运行方式,确保了机组的安全运行。在制订同类煤仓改造方案时,具有一定的参考价值。
In the coal-fired power plant, when coal is mixed with a certain proportion of slime or raw coal with high water content, the coal seam is often clogged during the process. The coal mill is forced to stop running and affect the stability of the boiler combustion. After analyzing the reasons of coal blockage, the air guns and rotary blocking cleaning machines are installed for coal hunkers, which improves the operation status of coal bunkers, and puts forward the seasonal operation mode of the blockage removal device, which ensures the safe operation of the coal generating units.
