Title of Invention	A REACTOR CHAMBER IN A FLUIDIZED BED REACTOR
Abstract	A fluidized bed reactor generating heat has in its bottom part a grid (5) for introduction of fluidizing gas into the reactor and walls (2) being made as waterwalls in which vertical water tubes are combined by flat plate material (15). The waterwalls are refractory lined (8) in their lower part to withstand erosion and heat. The water tubes are bent outwards at an angle to the vertical plane in the intermediate section between the uncovered upper waterwall section and the refractory lined lower waterwall section in order to minimizeerosion due to particles flowing downwards along the walls in the reactor.
