摘　　要：一次风管堵塞是煤粉锅炉的常见故障,如不及时疏通,轻则影响锅炉燃烧稳定,降低机组出力,重则引起锅炉灭火,严重时还会造成煤粉自燃,烧坏粉管。正确判断堵塞部位,采取恰当的疏通方法,可在短时间内疏通风管,既能减轻工人的劳动强度,又能保证人身与设备的安全。Primary air tube plugging is a common failure of the pulverized-coal-fired boiler.If not clear,ranging from the impact of boiler combustion stability,reduce the unit output,it will result in sever cases of spontaneous combustion of pulverized-coal,burned the powder tube.Therefore,judging the right position of plugging,adopting the appropraite dredging methods,the air tube can be dredged in a short period of time.It can not only reduce the labor intensity,but also ensure the security of personal and equipment.
