Minimum Spoutable Bed Height in a Screen

However, to date, there has been no report that a minimum spoutable bed height, or lower limit of the bed height, exists in any type of spouted bed. It was, however, found that there exists a minimum spoutabe bed height in a screen-bottomed spouted bed. The screen-bottomed spouted bed has a draft-tube, but it has no gas-inlet nozzle or orifice.
