• A comparison of VFB and CFB indicates that VFB has lower minimum fluidization velocity, higher bed voidage and more steady fluidization because big bubbles can not be formed in the bed.

    由于层中没有气泡生成,普通流化床(CFB)相比VFB具有初始速度大的床层空隙率,而且流化稳定

  • The phenomenon of agglomeration and its various influencing factors, the sintering minimum fluidization velocity, the parameter change of gasification when it was agglomeration are also presented.

    为了评价非磁性粘性颗粒在磁场流化床中的性能,测量最小流化速度、床层压力降床膨胀高度。

  • The minimum fluidization velocity has a minimum value when the frequency of sound waves approached 150 Hz, whereas it decreased as the sound pressure level was increased at the same sound frequency.

    气泡尺寸和鼓泡频率随声压增大减小,随声波频率增大减小后增大。
