PERFORATED PLATE DESIGN FOR A FLUIDIZED BED GAS DISTRIBUTOR

摘要

Abstract of the InventionThe present invention is directed to a perforated platedesign for supporting the particulate matter of a fluidized bed,through which the fluidizing gas flows, The perforations in theplate are formed by punching tabs or lids in the metal 50 as toraise the metal, but retaining the tab or lid. The constructionenables economical fabrication, permitting lateral gas flow throughthe openings, and protection against sifting of particles throughthe openings on shutdown or low load operation.C761080
