在对黄台电厂7号炉PM型燃烧器浓淡分离弯头结构进行模化实验研究的基础上,对弯头分离部件进行优化,确定了PM型燃烧器的较佳结构尺寸,使浓淡2部分浓度和流量分配更合理。经燃烧器改造,取得了大幅度降低锅炉最低稳燃负荷的显著效果。
On the basis of the experimental study on the structure of the PM-burner shading separation elbow in No.7 furnace in Huangtai Power Plant, the elbow separation components were optimized to determine the better structure size of the PM-type burner so as to make the shades 2 parts Concentration and flow distribution more reasonable. After the burner transformation, has made significant reduction in the minimum steady combustion load of the boiler significant effect.
