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 device for generating heat, with reduced emission of sulphur and nitrogen oxides. Combustion (1) of a fuel which contains sulphur and nitrogen is effected, the combustion effluents and particles of a fresh absorbent are introduced into a turbulence zone (9) upstream of an adiabatic desulphurisation zone (8) and the mixture produced is conveyed into a heat recovery zone (16). Part of the absorbent is recycled in the desulphurisation zone and the flow rate of fresh absorbent and of recycled absorbent is adjusted so that the temperature of this zone is 750 to 1000 DEG C. …IMAGE…
