A method and apparatus for reducing the amount of water-soluble acid pollutants contained in hot smoke or fumes produced by combustion, such as the incineration of household garbage, in the course of which dust is removed from the smoke and the smoke is then cooled before being released into the atmosphere. A heat exchange process involving a cold fluid is used in the cooling phase, in which the smoke is cooled to a temperature below its dew point so that the resulting total or partial condensation of the water vapor contained in the smoke traps acid pollutants.
