Abstract (en)
The combustion unit provides a circulation process and comprises a reactor chamber (R), where the lower part is provided with a grate structure (1) for forming a so-called fluidized bed. Fuel is supplied to the upper side of the grate structure into the fluidized bed, and means are provided for removing the coarse material of the fluidized bed from the grate structure and for supplying air into the fluidized bed. The combustion unit further comprises at least one particle separator which is provided with means for purifying the flue gases from solid material, the flue gases being generated in the fluidized bed and containing solid material. A return duct returns the solid material to the fluidized bed. The means (7, 8, 9) for supplying fuel to the grate structure and the means (11) for removing the coarse material in the fuel are formed into at least one group which penetrates the grate structure essentially at a same point. <IMAGE>
