A comparison of VFB and CFB indicates that VFB has lower minimumfluidizationvelocity, higher bed voidage and more steady fluidization because big bubbles can not be formed in the bed.
The phenomenon of agglomeration and its various influencing factors, the sintering minimumfluidizationvelocity, 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流化性能，测量了最小流化速度、床层压力降和床膨胀高度。

The minimumfluidizationvelocity 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.
