Abstract
For generating heat, with reduced emission of sulphur and nitrogen oxides, a fuel containing sulphur oxides and nitrogen is effected, the combustion burned and particles of a fresh absorbent are fed into a turbulent zone (9) upstream of an adiabatic desulphurisation zone (8); and the mixture produced is passed into a heat recovery zone (16). Part of the absorbent is recycled to the desulphurisation zone, and the flow rate of fresh absorbent and recycled absorbent is adjusted so that the temperature of that zone is from 750.degree. to 1000.degree.
