試驗研究發現,氣體噴嘴位置對氣固噴射器的輸送能力影響最大,氣體噴嘴存在某一最佳位置,而這一最佳位置與背壓、輸送物料特性和輸送風特性相關聯;氣固噴射器的收縮角對其輸送能力、內部靜壓分佈和輸送管阻力特性均有適量影響,收縮角增大對整個輸送系統均不利;在適當的輸送風范圍內,提高氣體噴嘴出口速度比擴大氣體噴嘴尺寸更為有利,但氣體噴嘴出口速度過高會增加氣固噴射器和輸送管內的能量損耗,給輸送帶來不利的影響;系統背壓與氣固噴射器的氣體噴嘴出口速度的選取有關。It is widely applied to the stove top, shove head, stove door and burmer brick, the binding of cooling - tube and groove bottom of the molten steel mouth of the heat stove, meantime empopyed in the field of the step stove bottom, the fir - proof wall of the circular stove, the cover, the protruding tape and sand sealing mouth of the equal - heating stove, the triangle, the spray gun and meltingiron groove of electric stove and also including fire - resistant material used in the refine stove and the stove door

當前噴嘴流束中的不穩定擾動波在穿過腔內的剪切層時,剪切層對其有選擇放大作用,形成渦環結構,剪切流動中渦環與碰撞壁撞擊,在碰撞區域產生壓力擾動波並向上游反射,在上游剪切層分離處誘發新的擾動的產生,當新擾動與原擾動匹配時,射流上游就被不斷地受到周期性激勵,腔內就產生流體自激振蕩並在後噴嘴出口形成脈沖射流。An aperture through which matter is discharged
輸出口,噴嘴物體被釋放出的開口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

在上游安裝一個帶有蛋形格柵的橢圓形流體噴嘴,可以提供一個精確構造簡單的空氣體積測量系統。在噴嘴的出口,空氣釋放時的風速分配是一致的靜壓為零。因此,噴嘴上游的總壓力是噴嘴出的速度壓力-於是就容易計算體積了。The influences of the inlet tube angle, backpressure and driving jet velocity on static pressure distribution in the gas - solid injector are calculated, and the effects of the inlet tube angle on particle bulk phase concentration and axial mean speed of particles in the gas - solid injector are analyzed firstly. the predicament caused by lack of measuring means on the particle velocity in experiments is solved
