Abstract
A fluidized bed combustion chamber (3) is provided with a perforated bottom plate (4) into which air nozzles (18, 19) are pressed in a manner similar to that used for tubes in a tube sheet of a heat exchanger. About one-third of the nozzles (18) are connected to a startup or auxiliary combustion chamber (14) for blowing in hot gas for heating the bed to the flash-point or ignition temperature of the fuel. Further, the bottom plate is insulated (20) between the nozzles. (FIGS. 1, 4.) A method of operating such a combustion chamber also is disclosed.
