Abstract

A fluidized bed apparatus where at least a portion of the apparatus comprises a membrane wall.

Claims

exact text as granted — not AI-modified
1 . A fluidized bed apparatus comprising:
 a vessel having a top and bottom, and defining a fluidized bed region; and,   an injection grid comprising fluid inlet ports positioned to provide a fluidizing medium to region;   wherein at least a portion of the fluidized bed comprises a membrane wall.   
     
     
         2 . The apparatus of  claim 1 , wherein the membrane wall comprises at least two independent flow paths. 
     
     
         3 . A method of fluidizing comprising:
 introducing a fluid into a fluidized bed of particles, and   providing heat to the particles through a membrane wall.   
     
     
         4 . A method of fluidizing comprising:
 introducing particles into a fluidizing bed region of a vessel; and,   introducing heat to the fluidizing bed region through a membrane wall.
