摘要
从循环流化床(简称CFB)边壁下降流的现象入手,首次揭示了边壁下降流的生成机理,并就床顶结构对边壁下降流的影响进行了试验研究.在此基础上,建立了边壁下降流内循环模型.通过分析和数学推导。
The mechanism of the particles descending flow near the bed wall in CFB is revealed for the first time, and an experiment is conducted about the effect of the bed top structure on the particles descending flow near the bed wall. Based on the test, the inner circulating model of the particles descending flow near the bed wall is set up. Through theoretical analysis and mathematical deduction, the inner circulating rate of the particles descending flow near the bed wall and the mean concentration of particles in axial section are acquired.
