FIELD: power engineering.
SUBSTANCE: invention relates to the field of power engineering, methods of fuel combustion in a fluidized bed of a solid heat carrier for heating gases, liquids and solids, as well as detoxification of gaseous, liquid and solid wastes. Method for fuel combustion in a fluidized bed of dispersed particles of an inert material into which a catalyst is continuously introduced from below and discharged from above, as a catalyst, fly ash particles generated by the combustion of fossil solid fuels are used, and a volumetric organizing nozzle is placed above the gas distribution grid. As a catalyst, fly ash particles formed directly in a fluidized bed of dispersed particles of an inert material when burned in a layer of fossil solid fuels are used. Particles of fly ash that are formed directly in the fluidized bed of dispersed particles of an inert material and the fly ash particles caught in the off-gas decontamination return into the fluidized bed as a catalyst.
EFFECT: high efficiency of fuel combustion.
