摘　　要：通过对邯钢喷吹用煤粉中配加一定比例的干熄焦地面除尘灰和高炉重力除尘灰后的煤质指标、热分解率以及燃烧性能的分析测定,探讨了高炉喷吹除尘灰是可行的。试验结果表明,在混合煤粉中配加5%～7%的干熄焦地面除尘灰或高炉重力除尘灰时,混合煤粉的燃烧率能满足高炉喷吹用煤的要求。同时,带来了很好的经济效益。It＇s feasible to mix dust ash in pulverized coal through out the analysis of the coal quality indexes, decom- position rate and combustion rate of the mixed coal with addition a certain percentage of dust ash （No. 1 coke dry quenching dust ash or No. 1 gravity dust ash）. It shows that the right mixed coal after adding 5% ~7% coke dry quenching dust ash or gravity dust ash into the mixed coal can be got, at the same time, it keep high combustion rate, which content with the BF. At the same time, it will bring a large economic benefits.

关 键 词：除尘灰 混合喷吹 燃烧率 置换比
