摘要
洁净煤技术是指在煤炭从开发到利用全过程中,旨在减少污染物排放与提高能源利用效率的煤发加工、燃烧、转化及污染物控制等新技术。循环流化床、增压流化床联合循环和整体煤气化联合循环等洁净煤技术均是比较具有竞争力的技术,其中,循环流化床技术在我国发展较快,现已有大型化的运行实例(1025T/H),目前正开发超临界循环流化床技术;整体煤气化联合循环的商业运行刚刚起步,华能绿色煤电天津IGCC电站工程250MW机组已经开始启动,正在进行前期工作;增压流化床联合循环技术还有待于完善。
Clean coal technology means the new control technologies which will reduce the discharge of pollutant and increase the utilization ratio of coal during the processing of coal. Circulating fluidized bed, boosting combined circulating fluidized bed and IGCC are all competitive technologies of clean coal, in which the technology of circulating fluidized bed is developing much fast in China. There is a practial example （1025 t/h） of large power station. Now the technology of super critical circulating fluidized bed is under devecopment and the commercial running of IGCC is just starting, for instance, 250 MW power unit of Tianjin green electric IGCC project, Huaneng has started now. The technology of boosting combined circulating fluidized bed is under perfection.
