循环流化床燃烧技术的发展

Development of Circulating Fluidized Bed Combustion Technique

循环流化床燃烧技术对我国燃煤污染控制具有举足轻重的意义。我国自上世纪80年代以来采取引进和自我开发两条路线,完全掌握了中小型循环流化床锅炉设计制造技术,在大型循环流化床燃烧技术上已经完成了150MW超高压再热循环流化床锅炉的示范工程,引进的300MW循环流化床锅炉进入示范实施阶段。阐明了超临界循环流化床锅炉是今后循环流化床燃烧技术发展极为重要的方向,是大型燃煤电站污染控制最具竞争力的技术。

Circulating fluidized bed combustion technology has a vital bearing in respect to control of pollution caused by combustion of coal. A review is presented of how China, since the 80's of last century, by technology licensing and self-reliant efforts, has adopted a twofold way of development, herewith mastering the art of designing and manufacturing small and middling circulating fluidized bed boilers. In respect to combustion technique, concerning large sized circulating fluidized bed boilers, the demonstration program of a 150 MM super-high pressure circulating fluidized bed reheat boiler has been completed while an imported 300 MM circulating fluidized bed boiler has entered the damanstration stage. The viewpoint is expressed that the supercritical circulating fluidized bed boiler is a vital goal of development of CFBC technique, readily conpetitive in respect to control of pollution caused by large coal firing power plants.
