Abstract (en)
[origin: DE19903510A1] According to the invention a material containing combustible components is burned or gasified in a circulating fluidized bed comprising a turbulence chamber (2), a solids separator (4) connected to the upper area of the turbulence chamber, a return line (6) leading from the solids separator to the turbulence chamber and a cooling device (15) for the indirect cooling of solids arriving from the solids separator. The cooling device comprises several fluidized beds (21, 22, 23) through which the solids pass one after the other. The first fluidized bed (20), into which the hot solids arriving from the solids separator are introduced first, is situated in a dechlorinating chamber (16). Fluidizing gas and at least one of the following dechlorinating additives: a) gaseous SO2 or a material which contains sulfur and releases SO2 in an oxidizing atmosphere, b) silicates and aluminium silicates, c) activated silicate, or d) other alkali-binding and HCl-releasing additives, are also introduced into the dechlorinating chamber in at least stoichiometric quantities so as to convert the alkali and metal chlorides contained in the arriving solids.
