Abstract:
In a filter dust melting furnace, the waste gases occurring in the interior (9) of the furnace are conducted outward through a waste-gas line (5) in the furnace top. Provided in the course of the waste-gas line is a quench (20) for the abrupt cooling of the waste gas by cold quenching air acting on it. To prevent deposits in the waste-gas line, the quench (6) is arranged in the section of the waste-gas line (5) which directly adjoins the furnace vessel (1) and extends essentially vertically, and means are provided for cooling the quench and the section of the waste-gas line (5) located downstream after the quench.
Abstract:
A heating element for a Deglor furnace includes a heating bar being surrounded by a protective tube. The protective tube is provided with a flange for mounting. The flange is formed by a separate ceramic ring or a metal clip and is permanently connected mechanically or chemically to an outer surface of the protective tube.
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.
