  1. A reasonable position of driving nozzle helps to achieve the maximum material flow that also depends on other parameters such as backpressure, properties of conveyed material and driving gas. it is observed that, an increase of convergent section angle is harmful to the pneumatic conveying system, and also influences on the mass flow rate of conveyed material, the distribution of static pressures in injector and the pressure drops of conveying pipe. in addition, within a reasonable scope of air mass rate, increasing the driving jet velocity is more advantageous than enlarging the dimension of driving nozzle

    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。
