摘　　要：通过研究操作条件对固体循环速率的影响 ,提出了新型的固体循环速率的双阀控制理论模型 ,基于循环喷动流化床中颗粒循环推动力的分析 。The new two-valve controlling theory model for solids circulation rate is proposed based on researching the influence of operation conditions on solids circulation rate. The method for predicting the maximum of solids circulation rate in recirculating jet-fluidized bed is obtained based on the theoretical analysis of solids circulating driving force.
