A vehicle recycling plant comprising a furnace, means for introducing a fuel into said furnace, a cupola disposed in close proximity to said furnace, and communicating therewith so that the hot gases discharged from the furnace are introduced into the cupola, means for conveying scrap vehicles above said furnace and into said cupola, substantially horizontal flue means communicating with both the cupola and the furnace for removing exhaust gases therefrom, a plurality of smelters disposed in said horizontal flue for melting down various components previously disassembled from the vehicles, a plurality of heat exchange means disposed in said horizontal flue for removing heat therefrom and converting it into various forms of energy, an enlarged horizontal flue portion disposed downstream of said heat exchange means, said enlarged flue portion containing a plurality of air vents for mixing ambient air with the flue gas and a scrubbing section for removing particulate material from the flue gas, vacuum pump means for drawing the flue gas through the horizontal stack and exhaust means for discharging the flue gas to the atmosphere.
A method for recovering distinct products from scrap vehicles, said vehicles comprising steel vehicle bodies, nonferrous and cast iron vehicle parts, combustible materials including tires and noncombustible materials including glass, which comprises stripping and separating said parts, tires and glass from said scrap bodies to obtain a stripped steel vehicle body, conveying said stripped vehicle bodies adjacent a furnace, burning a fuel in said furnace to produce a heated furnace gas as well as radiant heat which preliminarily heats said stripped body, further heating the preheated bodies in a cupola by means of said heated furnace gas to produce a steel melt and a slag, which are recovered therefrom, as well as a cupola exhaust gas, said exhaust gas from said furnace and said cupola combining to form a heated flue gas, drawing said heated flue gas through a substantially horizontal flue and in heat exchange relationship with a plurality of smelters and heat recovery units for recovering and using the heat from said heated flue gas, introducing ambient air into the flue gas downstream of said heat recovery units to further reduce the temperature of said flue gas, subsequently scrubbing the flue gas with water to substantially remove any particulate matter disposed in the flue gas and exhausting the cooled and cleaned flue gas to the atmosphere.
