中国水煤浆技术应用现状与发展前景

Application status and development prospect of coal water mixture technology in china

介绍了近年来国内水煤浆制备工艺、添加剂研究及燃烧、气化应用等领域取得的最新成果。根据我国水煤浆应用的发展格局(南方及沿海地区以燃料水煤浆应用为主,北方及主要产煤区以气化水煤浆为主),指出燃料水煤浆生产将向大型化浆厂及煤炭资源短缺的区域发展;水煤浆生产工艺(设备)将向洁净化、高效率、低能耗发展;制浆用煤选择向低阶煤、配煤和工业、生活废弃物发展。基于燃料水煤浆在节能、减排方面的重要作用,其在作为燃料代油、在城镇(供暖)炉窑上燃烧以及在水煤浆气化等领域具有广阔的发展前景,水煤浆管道输送技术也是今后水煤浆的发展方向。

The paper introduced new achievements of the domestic coal water mixture preparation technique, additive research, combustion, gasification application and other areas in recent years. According to the development situation of the coal water mixture application （fuel coal water mixture mainly in South China and Coast Area and gasified coal water mixture mainly in North China and main coal producing area） ,the paper pointed out that the production of fuel coal water mixture would be developed forward to a large scale and coal resources shortage areas.The production technology （equipment） of the coal water mixture would be developed forward to clean, high efficient and low energy consumption.The coal selected for the coal water mixture preparation would be developed forward to the low rank coal, blended coal and the industry and domestic waste material.Based on the important role of the fuel coal water mixture in the energy saving and emission reduction, the coal water mixture as the fuel to replace the oil would have a wide development prospect in the combustion of the township （heating supply） ovens,coal water mixture gasification and other areas.A pipeline transportation technology of the coal water mixture also would be the development orientation of coal water mixture in later.
