摘　　要：针对褐煤的高水分、低热值、易风化自燃、难以洗选、储存和运输等缺点,总结研究目前褐煤干燥脱水技术,并提出一套针对燃煤电站的褐煤干燥及其高水分烟气水分回收与余热来利用的方案,从而提高褐煤使用范围和经济性以适应当前能源紧缺及节能环保的能源局面。Aiming at the discadvantages of the lignite such as high moisture, low heat, easy effloresce, difficult cleaning, selecting, storage and transport, the thesis summarized the drying and dehydration technology of the lignite. Meanwhile the thesis raised the scheme, which for lignite drying, moisture recovery and heat utilization in the high moisture flue-ges used for boilers. The scheme improved the using scope and low costs of the lignite and adapted to the situation of energy resources shortage and environment protection.
