Abstract
A melting furnace for thermal treatment of heavy metal-containing and/or dioxin-containing special wastes, including a clog preventing system including a principal furnace vessel, which exhibits a melting tank for holding a melt; at least one feeder for feeding the material to be treated; a discharge chamber, which is at a spatial distance from the feeder, the feeder being connected gas-tight via a siphon to the melting tank; the principal furnace vessel and the discharge chamber having third heating elements in the form of bath electrodes, by means of which an electric current can be run through the melt and the siphon for additional heating of the melt.
Claims6
Melting furnace for thermal treatment of at least one of heavy metal-containing and dioxin-containing special wastes, comprising a principal furnace vessel, which exhibits a melting tank for holding a melt;
- at least one feeder for feeding the material to be treated;
- at least one discharge chamber, which is at a spatial distance from the feeder and which is connected via a siphon to the melting tank;
- at least one first heater, projecting into the interior of the furnace vessel, and at least one second heater projecting into the discharge chamber, wherein
- the principal furnace vessel and the discharge chamber have third heating elements in the form of bath electrodes, by means of which an electric current is run through the melt and the siphon for additional heating of the melt.
