火力发电新技术发展

Development of New Thchniques in Thermal Power Generation

火力发电在我国电力工业中占十分重要的地位。当前世界上广泛开展洁净煤燃烧技术的开发,追求燃煤机组的高效率和低排放,因此开发了一系列火力发电新技术,如超临界和超超临界机组、大型循环流化床锅炉、增压流化床燃气 蒸汽联合循环、整体煤气化燃气 蒸汽联合循环、燃气蒸汽联合循环等。该文简要介绍各种新技术的特点及国内外简况,供行业内有关工程技术人员参考。

Thermal power generation is playing a rather important role in China's power industry. All over the world clean combustion techniques of coal are being developed, aiming at high efficiency and low emission of coal firing power units. New coal firing power generation techniques, like supercritical and supersupercritical sets, large circulating fluidized bed boilers, supercharged fluidized bed gassteam combined cycles, gassteam combined cycles, gassteam combined cycles with integrated gasification etc. have therefore been developed. The paper presents a concise introduction to the special features of all the new techniques, as well as their status quo in this country and abroad, to serve as a reference for pertaining technical personnel of the trade.
