IGCC用煤气化技术的选择与发展

SELECTION OF PROCESS FOR INTEGRATED COAL GASIFICATION COMBINED CYCLE AND ITS DEVELOPMENT

根据ＩＧＣＣ对煤气化技术的要求及我国发展ＩＧＣＣ技术的特点，并结合煤气化技术的发展现状，在经过对各种煤气化技术进行分析和评价后认为：我国发展ＩＧＣＣ应选用Ｓｈｅｌｌ／Ｐｒｅｎｆｌｏ与Ｔｅｘａｃｏ加压气流床煤气化技术。针对ＩＧＣＣ技术的现状与特点，以及我国目前的具体情况，提出了发展这２种煤气化技术的设想，即统一规划、分段发展、引进吸收、慎重实施。

Shell/Preflo and Texaco Pressurized entrained-flow coal gasification processes are selected for integrated coal gasification combined cycle based on current status and characteristics of all types of gasifiers according to the requirements for IGCC and features of IGCC in China. Proposals for development of coal gasification technology are also presented by taking into account of technical and economic situation of China.at present. The proposal for development is overall planning, in-step development of the technology, introduction and absorption of new technology and cautious implementation.
