循环流化床燃烧(CFBC)作为一种最具发展前景的“洁净”煤燃烧技术,正在向着更高的参数、更大的容量发展。国外发达国家都在争先开发600MW以上容量、超临界蒸汽参数的大型循环流化床锅炉。在综述国外大型循环流化床锅炉技术基础上,对CFB锅炉的大型化结构和技术方案进行了系统分析,并提出了一种新的循环流化床锅炉大型化布置方案。 As the most promising “clean” coal combustion technology, circulating fluidized bed combustion (CFBC) is developing towards higher parameters and larger capacity. Developed countries are striving to develop large-scale circulating fluidized bed boilers with a capacity of more than 600 MW and supercritical steam parameters. Based on the review of the large-scale circulating fluidized bed boiler in foreign countries, the large-scale structure and technical scheme of the CFB boiler are systematically analyzed and a new large-scale layout scheme of the circulating fluidized bed boiler is proposed.
