Abstract
The present invention is concerned with an apparatus and method for continuous fluidization which comprises at least two cells connected by an aperture permitting the solid material to be introduced into the next downstream cell by fluidized horizontal flow, an isolated freeboard within each cell, at least two filter sticks contained within the isolated freeboard of each cell, and at least one blow back valve contained within each filter stick. The apparatus allows processing of materials that are typically difficult to fluidize by maintaining a substantially constant pressure difference between each isolated freeboard.
