摘要
本文主要对七种煤进行了显微组分的分析和分离。并对不同比例显微组分混合物的发热量、燃烧以后的残碳量进行测定,发观镜质组富集物比丝质组富集物发热量高;而燃烧后残碳量,丝质组富集物比镜质组富集物低。
In this paper, the analysis and separation of coal macerals mainly from seven coal samples were carried out. The calorific value, unburnt carbon after combustion of different kind of macerals concentrates were determined and we found that calorific value of vitrinite-rich is the best that fusinite -rich, as unburnt carbon in combustor also is the large for increased fuelloss; fusinite-rich decrease unburnt carbon in combustor.
