Abstract
The invention relates to a method and a device for melting down solid combustion residues such as slags, ashes and fine dusts from waste combustion installations (11) with solid, liquid and/or gaseous fossil fuels in a melting device. In order to reduce the necessary energy by combusting fossil fuels, the supply of the combustion residues (12) from the waste combustion installation (11) takes place directly into the filling opening (13) of the melting device. The melting device is designed as a shaft furnace (10) with a furnace space (14, 15) with a refractory lining, the combustion residues (12) being melted down by means of a fuel/oxygen mixture or by means of a fuel/oxygen-air mixture which is introduced into the shaft furnace below the combustion residue fill (21).
