Beschreibung
Zusammenfassung:	The invention relates to a process for reducing the polluting content of the flue gas from thermal processes, especially in the aluminium remelting process. To this end, finely divided metals and/or their oxides, hydroxides and/or oxihydroxides with an affinity for halogens are introduced into the heating flame but not in such quantities as would be necessary for the complete avoidance of the formation of dioxin and/or furane. To absorb the remaining pollutants, especially dioxins and furanes, the flue gas leaving the combustion chamber is sprayed with an incombustible oil-wateremulsion, preferably after the flue gas has passed through a preliminary washing process.
