摘要
对气固固循环流化反应器进行了研究。分析气固两相流在循环路径中的压力分布，并通过试验对其进行了研究。讨论测量细颗粒质量流率的方法，以此为基础研究了细颗粒藏量、流化气速、反应气速及固定床的空隙率对细颗粒质量流率的影响。讨论了用细颗粒移出强放热反应生成热的操作条件。
In this paper,a Gas Solid Solid Circulating Fluidization Reactor(GSSCFR)is studied.Firstly,the pressure distribution of gas solid flow along the circulating route is analyzed and experimentally studied.Then,the method of measuring the mass flow rate of powders is discussed.Based upon above research,effects on the mass flow rate of powders of inventory of powders,fluidization gas velocity,reaction gas velocity and void of packed bed are discussed experimentally. Finally, the operating conditions for the powders to remove the heat generated from the strong exothermal reaction are discussed.
