Abstract

There is provided a method and an apparatus for the operation of a fluidized-bed incinerator wherein a portion of the fluidized-bed medium (2) of the furnace is caused to pass a heat exchanger (8) during tapping from the combustion chamber of the furnace, and after cooling in the heat exchanger (8) is returned to the fluidized bed in the combustion chamber. The cooled fluidized-bed medium may be returned directly to the fluidized bed in the combustion chamber or it may be returned to the combustion chamber in an upper portion thereof and be allowed to fall through a distributor (13) so that it cools the zone above the fluidized bed at the same time as the medium is heated by waste gases from the combustion. The tapping of fluidized- bed medium is preferably controlled by a thermostat sensing the temperature of the fluidized bed. In an alternative arrangement the heat exchanger may be within a lower part of the fluidized bed. <IMAGE>
