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.
由于床层中没有大气泡生成，与普通流化床（CFB）相比，VFB具有更低的初始流化速度和更大的床层空隙率，而且流化稳定。
The interaction between gas and particles under different flow regimes, ranging from minimum fluidization to pneumatic transportation, was investigated in a vertical gas-solid flow system.
