PRIME STEEL SCRAP RECOVERED FROM WORN-OUT FREIGHT CARS--WITHOUT AIR POLLUTION

A mechanized facility was built to produce prime steel scrap from wornout railroad box cars. The cars are first passed to an incinerator that contains five box cars in intermittent transit through the burning chamber. During this transit, the wood lining of the cars is reduced to charcoal. Incinerator smoke is treated in afterburner chambers, then water cooled from 1800-200 F to about 600 F. Particulate matter is effectively removed before the cooled gases are discharged to twin 90-ft stacks. The final effluent contains only a few percent carbon dioxide, and the opacity of the stack gases seldom exceeds 0.5 ringelmann. From the incinerator the box cars are transferred to an oxy-acetylene torch burning rack for final disassembly. Any Charcoal remaining in the car skeltons is recovered for barbecuring briquettes.
