摘　　要：针对某电厂600 MW机组锅炉飞灰可燃物偏高问题进行详细分析,通过针对性的现场燃烧调整试验、降低煤粉细度以及实验室入炉煤质的热重分析,提出了相应的改进措施,使飞灰可燃物由原来的7.21%降低到4.95%,提高了机组运行经济性。The 600 MW unit boiler fly ash with high combustible matter is analyzed. By the specific site combustion adjustment test, reducing the pulverized coal fineness and laboratory charging quality of coal thermogravimetric analysis, the corresponding improvement measures are put forward. The improvement measures make fly ash cloud from 7.21% down to 4.95% and enhance the power generator unit operation efficiency.
