大型复合床式低倍率循环流化床热水锅炉的开发设想

Development Conceive of the Large Compound Type Lower Circulating Ratio Circulating Fluidized Bed Hot Water Boiler

全面分析了目前运行的大型循环流化床热水锅炉存在的问题,提出了采用塔式布置、多床复合、低流化风速、低循环倍率、低温气固分离等技术措施来实现循环流化床热水锅炉大型化的技术思想,并介绍了据此开发大型复合床式低倍率循环流化床热水锅炉的技术原理和结构特点。

The existing problems in operation of the large circulating fluidized bed hot water boiler is analyzed compre- hensively, and the new idea of designing the large circulating fluidized bed hot water boiler, adopting technology of tower pattern disposal, multibed composition, lower fluidizing velocity, lower circulating ratio, lower temperature gas solid separation, is brought up, and the technical principle and characteristic of the new type of the large compound type lower circulating ratio circulating fluidized bed hot water boiler, which will be developed, according to the new idea mentioned above, are introduced.
