向高炉喷吹烟煤,是扩大喷吹煤源的重要途径.对影响烟煤粉自燃和爆炸性能的因素进行了试验室研究,提出高炉喷吹烟煤的安全措施.工业试验时分析了喷煤设备的安全状况,采取控制气氛、温度和低压快速切断等措施,取得了喷吹安全正常,高炉技术指标良好的结果. The injection of bituminous coal into the blast furnace is an important way to expand the coal injection.A laboratory study on the factors affecting the spontaneous combustion and explosion performance of bituminous coal was put forward and the safety measures of blowing bituminous coal into the blast furnace were put forward.Industrial test, Of the security situation, to take control of the atmosphere, temperature and low-pressure rapid cut off and other measures to achieve the normal injection safety, blast furnace technical indicators of good results.
