With increase ofbedheight, air pressure and power consumption rise, expansion ratio of the bed decreases, but the density stability and critical fluidized velocity of the bed are hardly changed.
随着床层高度的增加,所需风压及功率增大,膨胀率有所降低,而床层密度的稳定性和起始流化气速几乎不变。

The effects of fluidization number, injection velocity, particle mean diameter and static bedheight on jet fluctuation are discussed.
研究了流化数、射流初始速度、颗粒平均粒径及静态床层高度对射流脉动特性的影响。

In practice, choosing the static heightof the bed layer and the frequency of the gas pulsation properly can increase the heat transfer coefficient.
