Abstract
For the separation of dioxins and furans from exhaust gases from combustion plants, particularly from refuse incinerating plants, a process is described in which the dust and the gaseous pollutants HF, HCl, SO.sub.2, and SO.sub.3 are first substantially entirely separated from the exhaust gases in known manner, the thus prepurified exhaust gas is then supplied to a wet-process electrostatic precipitator, and 10 to 500 mg activated carbon powder per sm.sup.3 are added to the prepurified exhaust gas immediately before it enters the wet-process electrostatic precipitator.
