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。
According to the theory of material balance, the selection principle of circulating fluidized bed boiler separator is analyzed. The test results of various separator boiler operating results show that the separator performance is an important factor affecting the combustion efficiency, but it can not solve all the problems of combustion efficiency. Review of the history of the development of circulating fluidized bed combustion technology, that the cooling separator is the development direction of China’s circulating bed. The successful development and operation of a low cost square separator at the 75t / h level provide the basis for the large size of the furnace. At present, the 130t / h and 220t / h design work is supported by the relevant national authorities Basically completed, 420t / h design is in progress.
