  • Patent number: 7267698
    Abstract: The invention is a method for producing hydrogen using a generator, heating the vessel that is part of the generator, loading waste comprising steel into the heated vessel, melting the loaded waste to a molten state using a non-transferred torch to cut and melt the waste and then using a transferred torch to maintain a molten metal pool, adding additional steel to raise the molten metal pool to a minimum depth, raising the temperature to 2000 degrees Centigrade, acquiring EPA approval, loading waste into the vessel at a defined rate, maintaining the molten metal pool further melting any non-melted waste into a molten status with the transferred torch, determining BTU content and gas flow, injecting steam into the vessel, flowing gas from the vessel through scrubbers into storage containers and collecting the hydrogen in a collection vessel.

  • Patent number: 7098421
    Abstract: The invention is a transferred or non-transferred plasma arc torch for use in a fuel gas generator system for generating electricity from waste, wherein the torch includes a torch housing, electrodes (one in a transferred torch, two in a non-transferred torch), a tubular sleeve member, a coolant flow path, a vortex mechanism, and a power supply circuit connected to the rear and front electrodes that generates an arc that is adapted to extend axially from the rear electrode through the vortical flow of gas and to an attachment located on the bore of the front electrode, and wherein the electrodes are metal coated in order to protect from wear during use.

  • Patent number: 7083763
    Abstract: A feed system for loading waste into a fuel gas generator system where the feed system is made of a walled container wherein the outer container back has an outer back hole and the inner container back has an inner back hole, and wherein the holes are aligned and a piston penetrates the holes, wherein the piston is connected to a plate moveably disposed in the container, wherein the piston is connected to sealable opening locks to apply pressure and retract the plate to a position against the back thereby providing a loading chamber to insert waste, a second piston connected to the door retracts the door for loading waste, at least one inert gas injector mounted to the container for flooding the loading chamber with inert gas, a liquid cooling system disposed in the walls of the container, and a controller for operating the locks, doors and sealable opening.

  • Patent number: 7017347
    Abstract: A system and method for converting waste into electricity. Hydrogen gas is produced from waste burned in a vessel including at least one plasma arc torch. Steam is introduced into the vessel to provide a source for the hydrogen gas. The hydrogen gas is then collected and stored for use as fuel in a boiler used to generate steam that produces electricity with a turbine-driven generator. The hydrogen gas may be routed through a scrubber system prior to storage. The system and method may include a waste feed system that employs a hydraulic ram and an inert gas atmosphere.
