摘要
在8 m3氧气高炉上进行了工业化试验,试验氧气高炉炉缸和炉身各设1排风口,炉缸风口喷吹氧气和煤粉,炉身风口喷吹预热的焦炉煤气。试验结果表明:氧气高炉可以实现全氧大喷煤炼铁生产,吨铁喷煤量可以达到450 kg,生产效率大幅度提高;炉身吨铁喷吹180 m3预热焦炉煤气以后,焦比降低90 kg,煤比降低50 kg,生产效率提高约20%;氧气高炉进行大规模工业化生产时,如果炉顶煤气循环利用,有望大幅度降低燃料消耗,节省成本。
Industrial test was carried out in 8 m3 oxygen blast furnace,whose hearth and shaft were respectively designed a row of tuyeres.Oxygen and pulverized coal were injected into the hearth tuyeres,and preheating coke oven gas was injected into the shaft.The test results show that the oxygen blast furnace is feasible to inject oxygen and massive coal,coal ratio can reach to 450 kg,and production efficiency can be greatly improved.When 180 m3/t preheated coke oven gas is injected to the shaft,coke ratio and coal ratio will decrease 90 kg and 50 kg respectively,and productivity will increase by 20%.If the oxygen blast furnace is produced in a commercial scale and top gas is recycled,it can significantly reduce fuel consumption and save cost.
