Abstract

Combustion of a particulate fuel in a fluidized bed (6) enclosed in a combustor (1) where impurities in the combustion gases generated during the combustion are taken up by an absorbent which is supplied in particle shape to the combustor (1) and wherein the invention comprises crushing absorbent particles with a diameter smaller than the size of 0.4 mm into a fine fraction with a grain size such that the diameter of the grains is smaller than the size of 50 mu m, whereafter the fine fraction is fed into the lower part of the bed (6), and wherein absorbent particles exceeding the size of 0.4 mm, the coarse fraction, are fed into the top part of the bed, near the surface (8) of the bed (6).
