关于中国洁净煤技术发展的若干思考

中国发展洁净煤技术应覆盖煤炭开发利用的全过程,针对多终端用户,优选实用的先进技术。中国的洁净煤技术是以提高煤炭利用效率、减少污染为目标,以煤炭洗选为源头,以煤炭气化为先导,以煤炭高效洁净燃烧和洁净煤发电为核心的技术体系。框架包括4个领域共12个方面:煤炭加工(选煤,型煤,水煤浆);煤炭高效洁净燃烧(流化床燃烧,高效低污染粉煤燃烧,燃煤联合循环发电);煤炭转化(气化,液化,燃料电池);污染控制(烟气净化,粉煤灰综合利用,矿区污染治理)。

SOME OF THE CONSIDERATION OF CHINA CLEAN COAL TECHNOLOGY DEVELOPMENT

In China, to develop the clean coal technology should consider the total process that including from coal mining to its utilization. And at the same time, the practical advanced technology will be selected optimally for different end use sectors. The development targets of clean coal technology is raising the coal utilization efficiency and reducing the environmental pollution. The technical development system may be considered as follows; coal preparation as a fountainhead, coal gasification as the precursor and high efficiency and clean coal combustion and power generation as the core. Depend upon this consideration, the technical frame is including four fields and twelve aspects technologies; coal processing (preparation, briquette and coal water fuel), high efficiency and clean combustion (fluidized bed combustion, high efficiency and low pollution pulverized coal combustion, integrated coal combustion combined cycle), coal conversion (gasification, liquefaction and fuel cell), pollution control (flue gas purification, coal ash comprehensive utilization and tackling pollution in coal mine areas).
