摘　　要：通过对水煤浆锅炉燃烧过程中常见的结渣问题进行分析与排查,初步确立添加除渣剂或降低炉膛燃烧温度两种方案并加以实施,以解决水煤浆锅炉燃烧过程中常见的结渣问题。试验研究表明,降低炉膛燃烧温度与添加除渣剂配合使用可改善锅炉的结渣情况。Through the analyzing and investigation of common slagging problems in coal water mixture boiler combustion, two plans （the deslagging agent addition or reducing furnace chamber combustion temperature） were established and practiced, to solute the common slagging problems in combustion process of coal water mixture boiler. The experiment research showed that adding the deslagging agent and reducing furnace chambe combustion temperature could improve the slagging circumstances.
