煤质对循环流化床锅炉细灰可燃物的影响

Influence of coal grade on combustible matter in fly-ash of CFB boiler

分析了燃煤的粒度分布及化学成分中挥发分及灰分对循环流化床锅炉细灰可燃物变化的影响,论述了细灰可燃物质量浓度偏高的原因,提出了具体的改进建议。

The influence of the particle size distribution,the volatile matter and the ash content of the fired coal on the combustible matter in fly-ash of CFB boiler was analyzed.The reasons of higher mass concentration of combustible matter in fly-ash were expounded;and concrete improvement proposal was given.
