ABSTRACT:
A method and apparatus for treating off-gas from a furnace for burning organic material in an oxygen deficient atmosphere by passing the hot exhaust gases from the furnace ladened with combustible and noncombustible organic material to a cleaning device, and thence passing the gases to a secondary furnace for combustion therein, and while in the cleaning device removing from the gas therein noncombustible material which would otherwise still be particulate matter in the exhaust from the secondary furnace. In another form of the invention, the exhaust gas from the furnace is passed to a burner and heat exchanger device having an inlet portion for heating the incoming gases, a combustion portion with air inlets for supporting combustion therein, and an outlet portion for cooling the gases, and thereafter the gases are passed to a quenching system.
