  • Fluidized bed combustor
    Patent number: 4455969
    Abstract: A fluidized bed combustor has its fluidizing chamber in thermal contact with a surrounding heat exchanger. A lined base portion of the chamber capable of containing the bulk of bed material while the bed is slumped is adapted to retard heat transfer from the bed. Thermostat linked devices in the bed and external load are arranged to switch the fuel and gas supplies to the bed so as to enable normal bed temperature to be attained without excessive heat removal to the heat exchanger.
