摘　　要：为提高喷煤比，充分发挥喷吹效益，安钢在1#高炉进行了为期3个月的富氧喷煤工业试验。通过风口区煤气和煤粉的取样分析以及炉尘的取样分析，研究了富氧率、煤粉粒度、煤比对煤粉燃烧率的影响和对炉况的影响，找到了氧煤合理的搭配关系，即对鹤壁烟煤，煤比140kg／t．Fe以下可以不富氧或少量富氧即能保证0．8以上的煤粉置换比，煤比160kg／t．Fe和富氧2．0％相对应，180kg／t．Fe则须富氧3％，粒度适当放宽对燃烧率的影响不大。To upgrade coal ratio and coal injection efficiency, a industrial test was taken in Nol BF in AnYang iron ＆ steel making group Co.. The result as follow： the knowledge of coal combustion which affected by oxygen enrichment, coal granularity, coal injection rate was get by sampling the gas and pulverized coat in raceway along the diameter ：to HeBi bituminous coal, when coal ratio less than 140kg/t,no or little oxygen enrichment is needed, coal ratio is about 160kg/t, 2 % oxygen enrichment is needed, coal ratio is about 180kg/t ,more than 3 % oxygen enrichment is needed, thus coal replacement ratio are maintained above 0.8.
