Abstract
A plate-type gas distributor for fluidizing a bed of particulate matter is described for use in elevated superficial velocity applications. The distributor comprises an assembly of plates or sheets formed into troughs and into deflector baffles which overlie the edge of adjacent troughs to form modules arranged in longitudinal rows. The troughs and the baffles are spaced in a predetermined manner by joining struts or ribs. A circuitous gas flow path is defined by the slit between each deflector baffle and adjacent troughs. The minimum spacing between adjacent troughs is chosen so that the fluid flow velocity through the trough spacing at design point is equal to or greater than the terminal velocity of the fluidized particles.
