洁净煤技术与环境

Clean Coal Technology and Environment

工业污染物排放是中国大气环境污染的主要原因，本文介绍了不同工业行业燃煤量、ＳＯ２、烟尘、粉尘排放量及不同行业的排放差别及特点，对选煤、型煤、动力配煤、循环流化床燃烧、烟气净化等洁净煤技术的经济、环境效益作了初步分析，指出选煤、型煤、动力配煤是发展洁净煤技术的优先领域，烟气净化、循环流化床燃烧是需要大量开发、推广的技术。

The discharge of industrial pollutants is the major source of atmospheric pollution in China.An introduction is made of the amount of coal combustion,emissions of SO2,smoke and dust.The discharge difference and characteristics from different industrial sectors are also discussed.The economic and environmental benefits of clean coal technologies such as coal benefication,coal briquette,coal blending,CFB and flue gas cleanup,are analyzed preliminarily here.It is pointed out that the priority areas for development of clean coal technologies are coal benefication,briquetting and blending.Meanwhile flue gas cleanup and the CFB technologies need to be developed and disseminated extensively.
