摘要: 锅炉原煤仓堵煤会使进入炉内的燃料量大幅度减小,若有2个及2个以上的煤仓堵煤,还会使锅炉发生熄火,严重影响锅炉的安全运行,同时也增加了锅炉的助燃用油。分析认为,造成堵煤的原因主要有煤种变化(煤的粒径变小、煤的水分增高)和输煤工艺系统局部设计不合理等因素。针对上述堵煤的原因,采取了应对措施,取得了良好的效果。

Abstract: The coal jamming in boiler minerun bin will greatly decrease asfired fuel quantity,the coal jamming occurred in two or more coal bins will cause the flameout fault in boiler, which will seriously influence the safety operation of boiler and increase the consumption of combustion supporting oil. the analysis that the reasons of coal jamming include the change of coal variety (decrease in the coal partical size, increase in the water content) and the unreasonable local design of coal handling system ,etc. Aiming at the abovementioned reasons, the countermeasures have been adopted, and the good results were obtained.

Key words: boiler mine-run bin, reason of coal jamming, countermeasure
