Abstract

In a fluidized bed furnace 2 that contains a combustion chamber 4 cooled by water tubes 24, upper and lower collectors 6, 8, as well as a nozzle bottom 9, the sealing of the combustion chamber 7 and the nozzle bottom consists of two plates that are welded together along the edges so that together they form a closed space that functions as a collector to which the water tubes in the wall 10 of the combustion chamber are connected. Collectors 6, 8 preferably consist of two round disk flanges arranged facing each other. <IMAGE>
