Abstract: The paper introduced the variation on raw material selection of the coal water mixture in China in recent years and the update research achievements ob tained from the additives and coal water mixture preparation technology.The paper stated the application effect of the fuel coal water mixture in the boiler and the heat C onducted oil boiler of the electric power stations. The paper had a discussion on the coal water mixture gasification technology features and application effect of the Tex ace coal water mixture gasification,the multi nozzles opposed type coal water mixture gasification and Tsinghua water cooling wall type coal water mixture gasification.B ased on the important significances of the fuel coal water mixture to the energy saving and emission reduction and the irreplaceable important role of the gasified coal water mixture in the chemical industry,the paper pointed out that the further development of the raw material coal sources for the mixture preparation,the development 0 f the new high efficient and energy saving mixture preparation technique and equipment,the research and development on the coal water mixture additives with a high p erformance price ratio,the development on the new coal water mixture combustion technology and gasification technology,to improve the coal conversion efficiency and to further reduce the production cost would be the research orientation of the late coal water mixture.
