摘要： A method of processing electric arc furnace dust includes the steps of preheating a portion of electric arc furnace dust to a temperature of at least 170 degrees centigrade by convection heating to form a preheated dust. The preheated dust is further heated by microwaves until a zinc in the preheat dust vaporizes to form a metal vapor and a residue. The metal vapor is then condensed.

摘要： A fume treatment system and method for treating a fume stream emitted from the mouth of a furnace chamber of a metal reclamation furnace system during a portion of the reclamation process includes an auxiliary hood that is smaller than the main overhead hood and is movable between an operative position over the furnace chamber mouth within the main overhead hood for collecting the fume stream emitted by the furnace chamber mouth and another position spaced from, the furnace chamber mouth. An incinerator is in fluid communication with the auxiliary hood when in the operative position. A fume stream blower causes the fume stream collected by the auxiliary hood when in the operative position to flow to the incinerator for incinerating hydrocarbons or other combustible compounds present in the fume stream during operation of the incinerator. A cyclone may be in the flow path between the auxiliary hood and the incinerator for removing particulates from the fume stream prior to entering the incinerator. Also a heat exchanger may be downstream of the incinerator for reducing the temperature of the fume stream exiting the incinerator prior to returning the fume stream to the main overhead hood for further processing.

摘要： An apparatus for preheating particulate material in which the particulate material is transferred from one or more upper storage bins to a circular lower chamber that has an outer, essentially annular, portion which serves as a gas flow passage. The particulate material is directed from the feed bin or bins into a plurality of essentially vertical cylindrical feed cassettes via intermediate feed ducts. The lower chamber has a flat roof which is in contact with the bottom portion of the vertical feed cassettes. The vertical feed cassettes are approximately evenly spaced on top of the outer perimeter of the flat roof. The particulate material is preheated in the annular flow passage by hot kiln gases flowing in countercurrent heat exchange relationship with the particulate material. Each feed cassette is completely segregated from its adjacent cassettes, and the bottom of each cassette is positioned over a hole in the flat roof of the lower chamber to thereby enable the particulate material to fall from each cassette into the annular flow passage section of the lower chamber. A plurality of particulate discharge mechanisms, the number of which correspond to the number of cassettes, discharges particulate material that has fallen into the annular flow chamber from the overhanging cassettes into a material outlet located in the floor located at the center of the lower chamber.

摘要： In a melting furnace (1), toxic, volatile chemical compounds from introduced filter dust from industrial incineration units are vaporized at about 1300.degree. C. and forced to leave the reaction space. The non-vaporizing residue forms a glassy melt which is discharged continuously or intermittently from the reaction space. Heating of the melt and of the filter dust is affected by resistance heaters in protective ceramic sheaths (4) above the melt (2). In order to prevent corrosion of the resistance heater protection sheaths (4) by exit gases (7) especially in the flow lee thereof, the exit gases are forced, by partitions (10) and an exit gas extraction pipe (9) with an inlet orifice (16) at a low level, to flow below the resistance heater protection sheaths (4) to an exit gas outlet (5). The partitions (10) reach with their underside (14) from a ceiling region (17) into the gas space of the melting furnace (1) preferably to a level lower than that of the underside (15) of the resistance heater protection sheaths (4).

摘要： A method for preventing deposits or build-ups of dust in off-gas channels for dust-containing off-gases from electrothermal smelting furnaces. This is done by blowing an additional gas tangentially into the furnace off-gas channels at the positions where build-ups or deposits of dust normally occurs. Hence a gas spiral is provided between the inner wall of the furnace off-gas channels and the dust-containing, hot furnace off-gas. Recirculated and cooled furnace off-gas is preferably used as additional gas. For open furnaces where the furnace off-gas is completely combusted before it enters into the furnace off-gas channels, air can be used as additional gas. The temperature of the additional gas is preferably kept below the sintering temperature of the dust in the furnace off-gas.

摘要： A recirculation device for recirculating a selected volume of preheated gas exhausted from a heating chamber in a mixture with fresh air back to the heating chamber. The device comprises a first passageway having an entrance and a pair of exits; a second passageway having a pair of inlets and an outlet; and a third passageway connecting one exit and one inlet. The other exit communicates with a preheated gas exhaust, and the other intake communicates with a source of fresh air. A back pressure damper is secured adjacent the other exit. A manual control assembly is connected to the back pressure damper so that the volume of preheated gas flowing into the preheated gas exhaust may be selectively determined. A mixing damper is secured adjacent the other intake. An automatic temperature dependent control assembly is connected to the mixing damper so that the mixture of preheated gas and fresh air entering the heating chamber is dependent upon the temperature in the heating chamber.
