Method and device for generating heat with desulfurization of effluents using sorbent particles with a fine particle size in an entrained bed

摘要

The invention relates to a method and a device for generating heat with reduced emission of sulfur oxides and nitrogen. a combustion is carried out (1) of a fuel containing sulfur and nitrogen is introduced the combustion effluent and particles of a fresh absorbent in a turbulence zone (9) upstream of a desulphurisation zone adiabatic (8) and sending the mixture produced in a heat recovery area (16). Recycling a portion of the absorbent in the desulfurization zone and adjusting the flow of fresh absorbent and recycled absorbent so that the temperature of this zone is from 750 to 1000 ° C.
