  • Fluidizing gravity conveyor with high temperature multi-layered fluid distributor member
    Patent number: 7553111
    Abstract: An apparatus for conveying fluidized high temperature finely divided dry material by gravity utilizes a multi-layered, gas permeable gas distributor member comprising (i) an upper layer a flat, rigid gas permeable, porous medium capable of withstanding temperatures up to about 2900° F. through which gas to fluidize the material will pass; (ii) a middle layer comprised of a gas permeable insulation material that maintains its physical integrity when exposed to temperature differentials ranging from about 500° F. to about 2900° F.; and (iii) a lower layer that supports the top and middle layers comprising a substantially flat plate having a plurality of openings therethrough through which fluidizing gas can pass.
