Fluidized bed calciner apparatus
A fluidized bed calciner is described including a shell, a fluidized bed disposed in the shell, a fluidized bed support member disposed in the shell, the support member in communication with the fluidized bed for supporting the fluidized bed. The support member has substantially rectangularly shaped slots for providing means for uniform fluidization, comprising: (a) parallel first channels traversing the top surface of the support member without interruption from one edge to the other edge thereof; and (b) parallel second channels disposed perpendicularly to the first channels and traversing the bottom surface of the support member without interruption from one edge to the other edge thereof, the first channels and the second channels forming a checkerboard lattice through which the fluidizing gas passes.
