Abstract:
A pyrolytic waste processing system comprising:a waste processing vessel including at least one plasma arc torch for pyrolizing waste in said processing vessel, the pyrolizing of waste generating product gases; a feed chamber for receiving waste and feeding the waste into said waste processing vessel; a scrubber in communication with said waste processing vessel for receiving, cooling and cleaning product gases generated within said waste processing vessel; a thermal oxidizer in communication with said scrubber for receiving and burning off product gases generated within said waste processing vessel; a gas supply unit for supplying gas to said plasma arc torch; a gas composition sensor for detecting a ratio of oxygen to product gases within said system; and a gas supply control unit coupled to said composition sensor and to said gas supply unit for causing said gas supply unit to switch the gas supplied to the plasma arc torch from air to an inert gas in response to signals received from the gas composition sensor indicating that the ratio of oxygen to product gases within said system is above a predetermined threshold.
