Abstract
A plate for fluid bed reactors to insure uniform distribution of the fluidizing gas, comprises a pair of spaced opposed plates having holes therethrough, the holes in one plate being staggered relative to those of the other plate. The peripheral holes are larger than the central holes. The holes in the upper plate have upper frusto-conical parts and lower cylindrical parts, while the holes in the lower plate have upper cylindrical parts and lower frusto-conical parts. The plates have central holes closed by frusto-conical plugs operable from outside the associated apparatus to discharge material from the plate.
