    Abstract: An apparatus and method for reclaiming contaminated scrap metal, more particularly an improved reverberatory furnace designed for melting scrap. The amount of hydrocarbons volatilized from the melting of contaminated scrap is measured and the fumes are passed into the main hearth for burning. As the amount of fuel value contained within the fumes increases, the amount of fuel provided to the burner is proportionally reduced while the amount of oxygen is kept constant. This will ensure that the amount of fuel and the amount of oxygen present within the furnace is completely burned without excessive free oxygen or unburned fuel building up within the furnace or furnace exhaust. The burner will be operating under lean fuel conditions or under fuel rich conditions such that the flame temperature is lower than at stoichiometric firing, whereby the burners create reduced NOx.

    Abstract: A reverse air flow oven for symmetrically heating product inserted within a heating chamber in the oven. The oven includes duct work configured symmetrically about the heating chamber, and a fan provides continuous circulation through the duct work and the heating chamber. The duct work also includes a pair of doors having complimentary configurations so that in one configuration, the air flow is in a first direction, and in the complimentary configuration, the doors cause air flow in the opposite direction. Further, a perforated plate regulates and equalizes air flow across the heating chamber and includes valve plates for controlling a build up of static pressure within the heating chamber.

    Abstract: An installation for the heat-treatment of parts includes a rotary hearth that can be rotated in a timed manner and which has an outer and an inner wall limiting a furnace chamber that is divided up into a heating zone and at least one treatment zone by vertically movable doors. The outer wall in the heating zone is provided with a closable opening for charging or discharging the furnace. The installation further comprises a transport device for transporting the parts into or out of the rotary hearth furnace and a quenching device. In addition, a second closable opening is disposed in the outer wall of the rotary hearth furnace in the last treatment zone. A sluice is disposed adjacent to the second closable opening and a quenching device is designed as a quenching bath and connected to the rotary hearth furnace via the sluice.
