清洁煤发电技术求索 ——华能天津IGCC示范工程进展综述 刘 宇 绿色煤电有限公司，北京市海淀区知春路甲48号盈都大厦A座21层 100098； Paving for Development of Clean Coal Technology: Progress Update of Huaneng Tianjin IGCC Demonstration Project LIU Yu GreenGen Co., Ltd. Floor 21st, Yingdu Building A, Zhichunlu A48, Haidian District, Beijing, P.R. China 100098 ABSTRACT：The dominant role of coal in energy supply could not be changed in a long period in China, which requires power generation technologies by coal should be developed in clean and low-carbon mode for sustainable development in future. As the primary course of GreenGen Project initiated by China Huaneng Group, Tianjin IGCC power plant is a flag project in demonstration of clean coal power generation technologies in China, which is projected to be on stream by the end of 2011. Up to now, construction of the project is going smoothly after ground-breaking in Jul. 2009 and the commissioning has been started. Based on the engineering practice, IGCC power plant could achieve pollutant emissions level of natural gas power plant, due to its technical nature in pollutant management and it is an incomparable advantage when competing with conventional pulverized coal power plant. As a result, IGCC should be developed with priority in economic developed regions, where the limit on environmental protection is usually stricter than other areas.
