摘要
褐煤是我国东北地区未来可利用的主要能源,但褐煤水分高,易风化自燃,发热量低,直接利用效率低,不利于长途运输,要大规模开发利用必须对其加工提质。本文介绍了我国蒙东地区褐煤资源状况,分析了国内外褐煤提质技术的发展状况,对我国褐煤提质加工的总体发展方向与趋势进行了初步探讨。
Lignite is the primary energy in northeast China available in the future,but it has high-moisture content,can be easily weathered and starts spontaneous combustion,produces heat low,and has the low efficiency in direct use,thus it is not convenient for long-distance transportation.It is necessary to improve its quality for large-scale development and utilization.In this paper,brown coal resources in China' s east Inner Mongolia are intro-duced.The development of lignite quality improvement in China and abroad is analyzed,and the overall development process and trends of China's lignite quality improvement are discussed.
