摘　　要：循环流化床锅炉燃烧技术在商业应用中具有清洁的特点,被认为是目前商业化程度最好的洁净煤技术;超临界技术能提高朗肯循环的效率,具有减少单位煤耗等优势。超临界CFB锅炉综合了超临界蒸汽循环和循环流化床两方面的优势,因而受到广泛的关注。分析了ALSTOM和FW两大公司的超临界CFB锅炉设计方案,并讨论了超临界循环流化床锅炉的国产化方向。Circulating Fluidized Bed combustion shows excellent environment emission characteristic in commercial application, which is believed to be the most commercial clean coal combustion technology; supercritical technology can significantly increase the efficiency of a Rankine cycle power plant, and reduce fuel consumption for a given output. SCCFBB combines advantages in the supercritical pressure steam circle and CFB combustion technology. Thus SCCFBB is paid more attention. This paper analyses the SCCFBB between ALSTOM and FW and points out the way of developing SCCFBB in china.
