摘　　要：在内径为０．１３９ｍ的有机玻璃床内，以空气为流化介质，分别对两类河砂作了喷动流化的不同操作──固定喷动气流量Ｑ＿ｓ（喷嘴内径０．０１９ｍ）、调节环形区流化气流量Ｑ＿Ｆ和固定Ｑ＿Ｆ调节Ｑ＿ｓ的操作，通过对床层压降变化的探讨．提出喷动－流化床的最优化操作。ifferent spouted-fluidized operations are carried out by using aie as fluidizing medium in a plexi-glass cylinder with 139mm I.D. for two kinds of river sand.The pressure drop changes are observedby the exporimental operations such as adjusting the flowrate of fluidization gas in the loop regime(Q_f)at a fixed spouting gas flowrate(Q_s)and nozzle inner diameter(19mm),or adjusting Q_s at afixed Q_F. Based on the experiments the, the optimized operation is proposed for the spouted-fluidized bed.
