Abstract: The specification describes a method and arrangements for operating fluidized bed combustors in particular boilers. In the described method and arrangements thermal energy carried away from the combustor by the flue-gas emitted therefrom is recuperated by passing the flue-gas through a scrubber in which it is scrubbed with water. The scrubbing water subsequently being used to pre-heat fluidizing gas fed to the fluidized bed in the combustor and/or working fluid fed to the boiler. Additional description is given of using a heat exchanger through which both flue-gases from the combustor and the working fluid fed to the combustor are fed such that the heat carried away from the combustor in the flue-gases is given directly to the working fluid fed to the combustor. In the described method and arrangements the fluidizing gas may be charged with water vapor and/or steam easing control of the bed.

Abstract: The specification describes a method and means for controlling operation of a fluidized bed combustion apparatus. In the proposals embodied in the invention the supply of combustion air fed to the fluidized bed is augmented by inert gas (preferably waste gas taken from a low temperature outlet of the apparatus) and the proportion of inert gas used to augment the combustion supporting air is variable in dependence upon the temperature of the fluidized bed in the apparatus and/or the thermal demand placed upon the apparatus. In described embodiments of means enabling the invention to be effected arrangements are described including an induced draft fan, coupled to the outlet for waste gas of the apparatus, for feeding waste gas to a mixer and the use of a two input mixer fan coupled to both atmosphere and a waste gas supply line connected to a waste gas outlet.
