Investigation on Improving Combustion Properties of Blast Furnace Pulverized Coal Injection
-
摘要: 在实验室就高炉喷吹用无烟煤中加入烟煤、助燃剂、富氧、提高风温等手段来改善煤粉的燃烧性能进行了研究。结果表明,在喷吹无烟煤中加入烟煤、助燃剂、富氧、提高风温等均能提高煤粉的燃烧性能。大量富氧效果最为明显,比较而言,混合喷吹,辅以富氧及加入助燃剂能够显著提高煤粉的燃烧性能。Abstract: To improve the combustion properties of blast furnace pulverized anthracite injection,a series of technical measures are tested in laboratory,which include add soft coal and combustion-supporting substance into anthracite,oxygen-enriched blast,enhance wind temperature etc.The results show every measure can improve the combustion properties,the effect of oxygen-enriched blast is especially notable.Injecting blended pulverized coal combined with oxygen-enriched blast and enhancing wind temperature can notably improve the combustion properties of blast furnace pulverized anthracite injection.
