| 摘要 |
The invention relates to a method and an apparatus for melting solid combustion residues, such as slags, ashes and airborne dusts, from refuse incineration plants (11) by means of solid, liquid and/or gaseous fossil fuels in a melting apparatus. In order to reduce the energy necessitated by the combustion of fossil fuels, the supply of the combustion residues (12) from the refuse incineration plant (11) takes place directly into the filling orifice (13) of the melting apparatus. The melting apparatus is designed as a shaft furnace (10) with a furnace space (14, 15) having a refractory lining, the combustion residues (12) being melted by means of a fuel/oxygen mixture or by means of a fuel/oxygen-air mixture which is introduced into the shaft furnace underneath the combustion-residue charging point (21). |
