循环流化床锅炉灰循环及浓度的探讨

Approaching on Ash Circulation and Concentration of CFB Boiler

阐述了循环流化床锅炉内、外灰循环的原理,根据循环流化床锅炉实际运行数据,对锅炉内、外灰循环灰量的量化问题进行了分析,并对内外灰循环作用的区别和关系进行了探讨,还结合锅炉灰循环倍率及浓度的设计以及在运行中的调整等情况提出循环流化床锅炉能否稳定运行的相关结论。

Tihis paper elabortes the internal and external ash circulation principle of CFB boiler,analyzes the magnitudization of internal and external circulation ash of boiler based on the practical operational data,discusses the distinguish and relations between internal and external circulating action and puts forward the related conclusion,which is the key of steady operation of CFB boiler for the design of ash circulationg ploidy ratio and concentration and circulation adjustment during operation.
