Abstract
A fluidizing apparatus comprises a vessel having an inlet, a plurality of outlets and a nozzle, through which a pressurized fluid can be fed into the vessel. The outlets are spaced at different heights from a base of the vessel and are controlled by valves enabling fluidized solids to be removed in layers from the vessel. In a further embodiment, a single outlet is raised or lowered to a desired position in the vessel.
