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.
