面对环境污染日益严重现状,2种新型洁净煤发电技术[增压流化床燃气-蒸汽联合循环发电(PFBC-CC)技术和整体煤气化联合循环发电(IGCC)技术]用于煤发电中.详细介绍了这2种技术的工艺流程,以及国内外洁净煤发电示范站的建立情况,并分析了这2种技术的优点和缺点.在洁净程度上比较,IGCC技术要优于PFBC-CC技术;从低碳经济的角度出发,提出了将燃烧后的尾气再次回收利用的新观点,从而实现零排放,真正达到低碳经济的目的.“,”Based on the serious environmental pollution, two novel clean coal technologies PFBC-CC and IGCC,have been using in coal power generation. The processes of the two technologies and the model power station at home and aboard were detailed, the advantages and disadvantages of the two technologies were also analyzed. The IGCC was superior to the PFBC-CC in clean production, and a new view was put forward, which was the coal-burning tail gas was recycled in order to realize the zero-emission and low-carbon economy.
