新钢9号高炉热风炉降低煤气消耗研究

摘要

The material and thermal balance was calculated and the heat utilization efficiency was ana -lyzed for hot stove of xingang No .9 blast furnace .Then the effects of different factors , including air temperature , gas temperature , air-fuel ratio and CO content of gas on dome temperature and gas con-sumption were researched .In addition , the actual production data was used to further discussion .%对新钢9号高炉热风炉的物料平衡和热平衡进行了计算,解析了其热量利用效率情况,进而定量分析了空气预热温度、 煤气预热温度、 空燃比和煤气中CO含量变化对拱顶温度及煤气利用的影响,并结合实际生产进行了分析.
