增压沸腾燃烧(PFBC)是近年来发展起来的清洁燃煤发电新技术之一,其原理是利用加压下的流化床燃烧锅炉实现燃气——蒸汽联合循环发电,从而大幅度提高发电效率,同时它又能满足日益严格的环保要求。本文简要地介绍了这种新技术的原理、结构、方案、优缺点、关键技术,经济性分析及国内外的进展,并提出加快国内开发这种新技术的建议。
PFBC is one of the clean coal-fired power generation technologies developed in recent years. Its principle is to use the pressurized fluidized bed combustion boiler to realize gas-steam combined cycle power generation, thereby greatly improving power generation efficiency , While it can meet the increasingly stringent environmental requirements. This article briefly introduces the principle, structure, program, advantages and disadvantages, key technologies, economic analysis and domestic and international progress of this new technology, and puts forward some suggestions to speed up the development of this new technology in China.
