The invention relates to a device for cleaning a gas mixture comprising contaminants. The device comprises a cylinder and a burner nozzle for supplying a fuel to be burned, said burner nozzle being embodied for directing into the cylinder a flame, wherein the flame is directed in a flow direction of the gas mixture. The device is characterized in that the device comprises cone shaped gas conductor with a relatively wide entrance for the gas mixture to be cleaned and a relatively narrow exit, The tapered shape is positioned in the flow direction and the narrow part of which is positioned near or within the supply side of the cylinder, with the proviso that the device is embodied for supplying into the cylinder the gas mixture to be cleaned partly through the cone shaped gas conductor and partly around the cone shaped gas conductor. The burner nozzle is positioned at the narrow side of the cone.

Disclosed is a plasma torch with a structure capable of performing reversed polarity/straight polarity operation, wherein the plasma torch is coupled to a melter and melts a waste material such as radioactive waste or industrial waste by generating and sustaining a plasma arc between electrodes, the plasma torch including: a rear electrode provided inside a torch pipe and electrically connected to become one of an anode and a cathode; and a front electrode provided at a front end of the torch pipe at a position adjacent to a front end of the rear electrode and electrically connected to become a remaining one of the anode and the cathode, wherein electrical connections of the rear and front electrodes are switchable with each other so that the plasma torch operates as a reversed polarity plasma torch or a straight polarity plasma torch.

An electronic device incorporating a high voltage power supply connected to a pair of metal plates spaced to maintain a continuous high current arc of electricity creating an Ion Plasma discharge for the purpose of vaporizing documents placed between the plates. Magnetic containment coils around the outside of the metal plates are phase synchronized to the magnetic field created by the Ion Plasma arc to maintain the position of the arc between the plates and to direct the position of the arc in a predetermined pattern to search for any material between the plates that has not been disintegrated.

A system for generating steam supplies of coal another material to one or more processing chambers. Each processing chamber includes a plasma arc torch that heats the material in the presence of water and a treatment gas at an extremely high temperature. A product gas stream is delivered from each processing chamber to a heat recovery steam generator (HRSG). Each HRSG generates steam that is used to drive a steam turbine. The processing chambers and HRSGs are fluidly connected so that the product gas streams moves from a processing chamber, to a HRSG, to another processing chamber, and then to another HRSG, etc. Within any of the HRSGs, or after the final HRSG, water in the product gas may condense to liquid water that may be redirected to any of the processing chambers. In addition, CO.sub.2 from the final HRSG may be redirected into any of the processing chambers to facilitate further reactions in the chambers.

A method of generating syngas as a primary product from renewable feedstock, fossil fuels, or hazardous waste with the use of a cupola. The cupola operates on inductive heat alone, chemically assisted heat, or plasma assisted heat. Cupola operation is augmented by employing carbon or graphite rods to carry electrical current into the metal bath that is influenced by the inductive element. The method includes the steps of providing a cupola for containing a metal bath; and operating an inductive element to react with the metal bath. A combination of fossil fuel, a hazardous waste, and a hazardous material is supplied to the cupola. A plasma torch operates on the metal bath directly, indirectly, or in a downdraft arrangement. Steam, air, oxygen enriched air, or oxygen are supplied to the metal bath. A pregassifier increases efficiency and a duct fired burner is added to a simple cycle turbine with fossil fuel augmentation.

A method of generating syngas as a primary product from renewable feedstock, fossil fuels, or hazardous waste with the use of a cupola. The cupola operates selectably on inductive heat alone, chemically assisted heat, or plasma assisted heat. Additionally, the operation of the cupola is augmented by the use of direct acting carbon or graphite rods that carry electrical current for additional heat generation into the metal bath that is influenced by the inductive element. The method includes the steps of providing a cupola for containing a metal bath; and operating an inductive element to react with the metal bath. Feedstock in the form of a combination of fossil fuel, a hazardous waste, and a hazardous material is supplied to the cupola. A plasma torch operates on the metal bath selectably directly and indirectly. Steam, air, oxygen enriched air, and oxygen are supplied in selectable combinations.

A device for processing waste is described herein that comprises an ion generator, a furnace chamber, a heat exchanger, a pollution control system, and a chimney. The ion generator converts atmospheric air into an ionized gas and the furnace chamber thermally decays the waste by combining the waste with a product of an interaction of the ionized gas and heat generated by the furnace chamber. The heat exchanger cools the excess gas. A wet scrubber system removes heavy metals and/or acid gases from the cooled excess gas to generate scrubbed excess gas, and a fixed bed coke system detoxifies the scrubbed excess gas by converting carbon monoxide, water, and steam in the scrubbed excess gas to carbon dioxide and hydrogen, and removing remaining acid gas, a remaining heavy metal, and/or a remaining dioxin from the scrubbed excess gas. The chimney transfers remaining scrubbed excess gas out of the device.
