潞安漳村喷吹煤添加剂的选择

Chemical additive selection of Lu'an Zhangcun injection coal

采用热重法对潞安漳村喷吹煤粉在不同添加剂下的燃烧性和反应性进行研究。实验结果表明:生石灰、熟白云石粉对漳村喷吹煤粉的燃烧性和反应性起促进作用,其中生石灰的促进效果较为明显,且当生石灰的添加比例为4%时促进效果最为显著,而白云石粉对漳村喷吹煤粉的燃烧性起抑制作用。

The combustion property and reactivity of Lu＇an Zhangcun pulverized coal adding different chemical additives was studied using TGA method. The results showed that： the quicklime and mature dolomite powder could enhance the coal combustion and gasifying reaction （the quicklime could enhance more obviously）. The most dramatic improvement would happen when 4% of quicklime was added, while the mature dolomite powder would restrain the combustion of Zhangcun injection coal.
