Abstract
An apparatus for vitrifying heavy-metal-containing residues having a chlorine content above 10% by mass, in particular from flue gas cleaning, which are melted in a melting furnace, the constituents which cannot be incorporated into the melt are separated in the main furnace into two fractions, the first fraction comprising the readily volatile components and the second fraction comprising the salt-like less volatile components, and the first fraction is evaporated off, conducted out of the furnace together with the exhaust gas and collected as condensate, and the second fraction is separated from the surface of the melt as liquid salt and is discharged.
