摘要
对3种单一煤及按质量比1:1组成的混煤进行了哈氏可磨性指数HGI测定及热天平燃烧试验,结果表明混煤的可磨性与各组成煤种的可磨性之间不存在线性关系,而由于各组成煤种可磨性的不同造成了混煤煤粉粒径的偏析,影响了混煤的燃烧。
The grindability of three single coals and blended coals mixed with ratio 1:1 are measured by the Hardgrove Grindability Index (HGI). It is found that grindability was non-additive especially when coals of very different HGI are blended. While, because of the different grindability of the single coals, there is a segregation of particle size, which will affect the combustion character of blended coals.
