摘　　要：针对"W"型火焰锅炉飞灰可燃物含量升高的情况,从设计、煤质、煤粉细度及运行方式四方面分析,认为煤粉细度变粗、分离器堵塞、运行氧量不足是飞灰可燃物含量升高的主要原因,并介绍处理措施及效果。According to the problem of increased combustible of fly ash in ＂W＂ type fired boiler, this paper analyzes the causes from four aspects of namely design,coal,coal fineness and running mode,concludes that coal powder coursing, coal impurities which blocking mill separators, low running oxygen are main reasons, and at last, shows the countermeasures and effect.
