ABSTRACT:
A gas distributor for fluidizing a bed of particulate matter which provides for minimum dissipation of particle energy from a particulate-laden gas stream on a distributor surface is disclosed. The gas distributor allows the particulate-laden gas stream to contact the surfaces of the distributor at about 90.degree. or 0.degree. which are angles of impact for low erosion. Opposing particulate-laden gas streams are made to contact each other which removes particle kinetic energy while minimizing erosion before fluidizing the bed of particulate matter.
A method to minimize erosion of a gas distributor for fluidizing a bed of particulate matter from a particulate-laden gas stream is also disclosed.
