It was found that the ultra - fine powder can flow smoothly in a spouted bed with a draft tube under some sorts of design parameter and operating condition, thus a new effective method to improve fluidization quality of the ultra - fine powders is obtained ; at higher supplied gas velocity, an increase in the solid circulation rate is observed ; the extent of the distance between the nozzle and the draft tube inlet result in the promotion of the solid circulation rate ; the solid circulation rate increase with increasing the draft tube diameter or the bed mass ; the gas bypassing is nearly zero in the present work ; and the solid flow in the annulus is observed as a moving bed
結果表明：在一定的床層結構和操作條件下，超細粉可以在導向管噴動床中實現平穩流化，從而為改善超細粉的流化質量提供了一種有效的新方法；固體循環速率與噴動氣流量、導向管直徑、導向管底部與噴嘴出口間距以及床層裝填量成正比；氣體則基本上不存在「旁路」現象；環隙區中的顆粒流動表現為一移動床特徵。
