摘　　要：煤粉锅炉燃烧时,结渣是锅炉一直存在的问题。锅炉设计煤种和燃烧方式存在着不适应,就容易导致炉膛结渣。锅炉燃烧煤种偏离设计煤种,而对燃烧的煤种特性分析不够深入,锅炉在燃烧时,由于燃烧器本身的调整不能适应煤种多变的情况,最终将导致炉膛结焦,甚至出现因结渣而引发锅炉停运。针对670 t/h锅炉因煤种和燃烧方式不相适应而导致炉膛结焦的原因进行分析,并对锅炉燃烧器进行重新布置,改善炉膛结焦。The slagging is existing problem in boiler as burning coal. It is easy lead to slag for not adapting combustion system to the design coal. It is not only slagging in boiler but also shuting down boiler for burning coal with deviating design, lacking in-depth anlysis the character of coal, not adapting combustion system to parts of coals and so on. This paper anlyses slagging of 670t/h boiler for not adapting combustion system to the design coal, and arranges the burners again to improve slagging in boiler.
