The new technology of coal combustion in fluidized bed has been implemented in some power plants, recently. The temperature of this process is much lower, about 900 °C, thus its phase composition and properties are totally differenL At low combustion temperature only the dehydroxylation of clay minerals occurs and the produced amorphous substance is one of the main components of fluidized bed ash [106] (Fig. 7.20). Simultaneously with coal combustion the flue gas desulphurization is performed and the sorbent, usually calcium carbonate, is introduced into the fluidized bed. Becarrse that the excess amount of sorbent must be added (Ca/S...
