基于密相区热平衡的CFB锅炉物料循环倍率测试方法

Test Method for CFB Boiler Circulation Ratio Based on Dense Phase Heat Balance

固体物料的循环倍率是ＣＦＢ锅炉设计和运行中非常重要的技术参数．以密相区为控制体．通过对控制作物料平 衡及能量平衡的分析，建立了热平衡式；根据ＣＦＢ锅炉的特点合理简化之后得出循环倍率的表达式，由该表达式经过常规 的锅炉测试就可测定ＣＦＢ锅炉循环倍率．

In this Paper heat balance equation is set up for dense phase region of CFB boiler according to which circulation ratio may be test test some reasonable simplifications
