Abstract
An apparatus for treating waste material that comprises four major cooperating subsystems, namely a pyrolytic converter (24), a two-stage thermal oxidizer (26), a steam generator (28) and a steam turbine (30) driven by steam generated by the steam generator. In operation, the pyrolytic converter is uniquely heated without any flame impinging on the reactor component and the waste material to be pyrolyzed is transported through the reaction chamber of the pyrolytic converter by a pair of longitudinally extending, side-by-side material transporting mechanisms (42, 43).
Claims10
An apparatus for treating waste material comprising:
- a thermal reactor having an inner chamber that carries a waste stream, and an outer chamber that provides heat to the inner chamber to sustain pyrolysis, wherein the inner chamber is gaseously sealed from the outer chamber in the thermal reactor;
- a first conveyor disposed within the inner chamber that transports the waste stream through the inner chamber, and includes a first screw section;
- a thermal oxidizer that burns gases derived from the inner chamber, and produces exhaust gases that are vented to the outer chamber of the thermal reactor in a manner that heats the waste stream in the inner chamber;
- and
- wherein the thermal oxidizer further comprises first and second sub-chambers divided by a baffle that controls the flow of gases between the first and second sub-chambers, and wherein a pressure senor is operably associated with the baffle that senses a pressure differential between the first and second sub-chambers.
