Abstract
Method and apparatus are disclosed for producing a useful stream of hot gas from a fluidized bed combustor and controlling bed temperature by introducing cooling gas into the freeboard region of the combustor. The cooling gas is introduced by a plurality of inlet ports located within the combustion chamber or about its periphery. The cooling gas contacts particulate matter in the freeboard region, extracting heat therefrom. Cooled particulate matter either falls back into the bed or is returned to the bed from a separator downstream of the combustion chamber.
