A fluidising apparatus comprises a vessel (28) having an inlet (14), a plurality of outlets (42,44,46,48) and a nozzle (10), through which a pressurised fluid can be fed into the vessel. The outlets (42,44,46,48) are spaced at different heights from a base of the vessel (28) and are controlled by valves (52,54,56,58) enabling fluidised solids to be removed in layers from the vessel (28). In a further embodiment, a single outlet is raised or lowered to a desired position in the vessel (28). |
