摘　　要：介绍了油团聚技术高效脱除煤中灰分的研究过程；探讨了煤炭粒径、用水量、起泡剂的种类等影响煤炭灰分脱除率的主要因素。实验结果表明，灰分含量为３０．７９％的烟煤，灰分脱除率可达８６．８％Introduced is the research procedure of high efficient coal ash reduction by oil agglomeration; discussed is the influence on coal ash reduction efficiency by feed size, water and frother consumption. Experiments denote that for a bituminous containing 3079% ash, ash removal was up to 86.8%.
