ABSTRACT:
This invention relates to an improved method of controlling temperatures within a cleaning or reclamation furnace which is normally used to reclaim metal parts contaminated with combustible materials by pyrolyzing the combustible materials. A reclamation furnace usually includes a primary heat-input burner employed to heat the contaminated parts in the primary heating chamber, an afterburner chamber contained within the heating chamber having a secondary burner to burn volatile gases which are given off by the combustible materials as the parts are heated, and two separately-controlled automatic valve and spray nozzle assemblies connected to the primary heating chamber. Each nozzle assembly is connected to a pressurized water source to deliver a water-spray injection into the heating chamber. First and second temperature sensors are located in the discharge stack leading from the afterburner chamber and in the furnace heating chamber respectively to actuate either one or both of the separately-controlled automatic valve and spray nozzle assemblies responsive to the temperature of the burned stack gases and the furnace interior temperature.
