Title: Control method for a reclamation furnace

Abstract

A method is presented for preventing fires and explosions and thus controlling excess temperature within a burn-off or reclamation furnace including a water injection nozzle within the furnace, an automatic valve assembly connected to a source of water under pressure to turn the water on and off, an input burner to heat contaminate materials, an afterburner to burn volatile gases given off by the contaminate materials as they are heated, a temperature sensor located in the discharge from the afterburner to actuate the automatic valve assembly open and closed responsive to the temperature of the discharge. The temperature of the discharge depends on the rate of emission of volatile gases from the contaminate material so that if a high emission rate causes a predetermined temperature to be exceeded the valve assembly opens and the water injection nozzle sprays water on the contaminate materials to cool them and decrease the emission rate until the valve assembly closes.
