对于大容量电站循环流化床(circulating fluid bed,CFB)锅炉技术,我国现在处于引进国外和自主开发相结合的阶段,国外的先进经验值得借鉴。介绍了300 MW等级的旋风筒CFB锅炉的简化,整体式水/蒸汽冷却紧凑型分离器CFB锅炉的开发,CFB锅炉部件的设计、制造、安装模块化,CO2接近零排放的CFB技术的发展等当前国内外大容量CFB技术的发展方向,并对超(超)临界CFB锅炉及生物质CFB锅炉的最新进展进行了综述,以供国内同行参考。
As for the circulating fluidized bed (CFB) boiler technology of large capacity power plants, our country is now in the stage of combining the introduction of foreign countries and independent development. The advanced experience abroad is worth learning from. This paper introduces the development of simplified, monolithic water / steam cooled compact separator CFB boiler with 300 MW cyclone CFB boiler, the development of CFB boiler design, manufacture, installation and installation, CFB technology close to zero emission of CO2 At present, the development trend of large-capacity CFB technology at home and abroad is summarized, and the latest progress of supercritical CFB boilers and biomass CFB boilers are reviewed for reference of domestic counterparts.
