Rotating fluidized bed combustor
A rotating fluidized bed combustor particularly adaptable for mounting on conventional gas turbine engines comprising an annular fluidized bed, defined by inner and outer spaced apart coaxial, cylindrical, perforated walls, which rotates about the longitudinal axis of the cylinders. Compressed air and solid or liquid fuel enter the bed through the outer perforated wall and fluidize the bed. The air reacts with the fuel within the bed to produce hot combustion gas which exits the bed, together with unreacted compressed air, through the inner perforated wall. When employed with gas turbine engines, the gases exiting the bed are directed into the guide vanes of the gasifier turbine. Cooling tubes pass substantially longitudinally through the rotating fluidized bed and compressed air is directed through the tubes to absorb combustion heat from the bed.
