摘　　要：通过对酒钢高炉瓦斯灰和污泥进行煤岩显微组分分析,酒钢高炉瓦斯灰和污泥中的碳元素含量都比较高,来源于焦炭的碳元素比例要高于来源于未燃煤粉的碳元素比例,且随着喷吹煤比升高碳元素在高炉除尘灰中的含量也随之升高。By analyzing the macerals of blast furnace dust and sludge in Jiuquan I ＆ S Co. LTD, the carbon content is high in blast furnace dust and sludge. And we find the carbon that come from coal is more than come from unburned pulverized - coal, further more the carbon content in the blast furnace dust is increasing with the pulverized coal injection rate added.
