摘　　要：根据物料平衡理论分析了循环流化床锅炉分离器的选取原则，对各种分离器锅炉运行结果的测试认为分离器性能是影响燃烧效率的一个重要原因，但不能解决燃烧效率的全部问题。对循环流化床燃烧技术发展历史的回顾，认为冷却式分离器是中国循环床的发展方向。低成本的方形分离器在７５ｔ／ｈ等级的成功研制和运行的良好性能为该炉型的大型化提供了依据，目前在国家有关部门的支持下，１３０ｔ／ｈ和２２０ｔ／ｈ的设计工作已经基本完成，４２０ｔ／ｈ的设计正在进行中。The separator choice method in circulating fluidized bed (CFB) boiler design is discussed based on material balance theory. According to the test of several CFB boiler with different separators, the author believed that the performance of separator is one of the key factor which influence the combustion efficiency, but it is not the only one. The development history of CFB combustion technology made the author sure that the CFB with cooled separator type is a development direction in China. The development of 75 t/h CFB boiler with low cost water cooled square separator and its excellent function gave evidences for scaling up design. Now it is supported by The State Departments, the design of 130 t/h and 220 t/h CFB boiler of this type had been finished and the 240 t/h is designing.
