Fluidized bed combustion: a method of burning particulate fuel such as coal in which the amount of air required for combustion far exceeds that found in conventional burners.

流化床燃烧，沸腾床燃烧：一种燃烧颗粒燃料(如煤炭)的方法。燃烧时的空气需求量远远超过常规燃烧器。

This technique is widely applied to granule core coating because due to high evaporation rate of fluidized bed, the granule could be coated when suspended in the air stream.

由于流化床设备有极高的蒸发效率，颗粒悬浮在气流中，进行包衣，使得这一技术能广泛地适用于粒芯包衣。

With increase of bed height, 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。
