Abstract
The apparatus of the present invention is a gas distributor system for installation beneath a fluidized bed, said distributor system containing a sift trap chamber for accumulating solids filtering through the distributor plate gas inlet means. The apparatus contains no internal parts in direct contact with the fluidized bed, and thereby limits erosion of the distributor thus reducing greatly the cost of fabrication and maintenance.
