ABSTRACT:
A mechanism for the prevention of distributor plate pluggage by dust-laden gases in multistage fluidized-beds is disclosed. Slanted tubes are used to control the flow of gases into a fluidized bed, where the angle between the slanted tube and the distributor plate is less than the angle of repose of the bed solids.
