浅床也称浅床流化床。采用少装固体颗粒、尽量减少浓相区的高度的方法构成的流化床。
特别是对于大直径、浅床层、低压降的填料塔，分布器的流场均布性能尤为重要。
The flow distribution capacity of distributors is most important, especially for tower with large diameter, shallow bed or low pressure drop.
由于所用的床层极浅，其结果不应与细颗粒的正常流化床性状相联系。
Because of the extreme shallowness of the beds used these results need not relate to the behavior of normal fluidized beds of fine particles.
