摘　　要：在电站的锅炉设备运行过程中,对于煤种的选择,会使整体的锅炉设计产生较大的差异性。褐煤本身具有一些特别的属性,所以和一般的锅炉运行中所掺烧的煤种相比,有很大的不同之处。对此,对使用该煤种提高电厂锅炉的运行效率的所有措施进行了分析,其中需要利用合理的控制方式调整褐煤的掺烧比例,保证其能够达到满负荷工作状态下的40%~60%,对提高机组的稳定性和安全性提出了相应的设备功能的改造建议。During the operation of the boiler equipment of the power station,the choice of coal type will make the overall boiler design a greater difference.The lignite coal itself has some special properties,so it is quite different from the coal that is burned in the normal boiler operation.In this regard,the article analyzes the measures needed to use this coal to improve the operating efficiency of power plant boilers.It is necessary to use a reasonable control method to adjust the proportion of lignite blending to ensure that it can reach full-load working conditions.From 40% to 60%,corresponding equipment function modification suggestions are put forward to improve the stability and safety of the unit.
