摘要
为了改善煤粉燃烧性能、强化煤粉燃烧 ,将添加剂混入攀钢喷吹用的煤粉后进行燃烧试验。根据高炉生产特点 ,选择MnO2 ,MgCO3,MnCO3,NaCl(食盐 ) ,MgCl2 ,生石灰 ,CaF2 ,转炉尘作为添加剂。实验室的动态燃烧实验表明 :混加适当的添加剂可以缩短煤粉着火时间 ,提高煤粉燃烧率。几种添加剂中 ,NaCl及生石灰的助燃效果较明显。添加剂配比的确定应考虑其对高炉冶炼的影响。
In order to improve combustion properties and enhance combusion of pulverized coal (PC),the combustion experiment was carried out after the PC used for PZH Steel blast furnace was mixed with different additives.Based on the feature of blast furnace operation,MnO 2,MgCO 3,MnCO 3,NaCl(table salt),MgCl 2,quick lime,CaF 2 and converter dust were chosen as additives.The results of the dynamic combusion experiment show that the ignition time of PC was shortened and the burning ratio was increased when PC is mixed with appropriate additives.The combustion-supporting effects of NaCl and quick lime were obvious among several additives.The amount of additive in PC should be determined on the basis of its effect on blast furnace operation.
