Publication number: 20090114178Abstract: A plasma assisted combustion device includes a body formed of a dielectric material that defines a conical-shaped plasma chamber. A conical-shaped ground electrode is positioned in the plasma chamber. At least one support structure is coupled to the conical-shaped ground electrode so as to suspend the ground electrode in the plasma chamber thereby forming a gap between an outer surface of the body and the ground electrode. The support structure comprises an insulated material that is positioned on an outer surface so as to reduce the probability of generating an undesirable electrical discharge. A hot electrode that is energized with a high voltage that strikes a plasma discharge in the gap is positioned proximate to the plasma chamber.

Publication number: 20060193759Abstract: A device for processing gases includes a cylindrical housing in which an electrically grounded, metal injection/extraction gas supply tube is disposed. A dielectric tube surrounds the injection/extraction gas supply tube to establish a gas modification passage therearound. Additionally, a metal high voltage electrode circumscribes the dielectric tube. The high voltage electrode is energizable to create nonthermal electrical microdischarges between the high voltage electrode and the injection/extraction gas supply tube across the dielectric tube within the gas modification passage.

Patent number: 6906280Abstract: A fast pulsed nonthermal plasma reactor includes a discharge cell and a charging assembly electrically connected thereto. The charging assembly provides plural high voltage pulses to the discharge cell. Each pulse has a rise time between one and ten nanoseconds and a duration of three to twenty nanoseconds. The pulses create nonthermal plasma discharge within the discharge cell. Accordingly, the nonthermal plasma discharge can be used to remove pollutants from gases or break the gases into smaller molecules so that they can be more efficiently combusted.Type: GrantFiled: March 21, 2003Date of Patent: June 14, 2005Assignee: The Regents of the University of CaliforniaInventor: Louis A.

Publication number: 20040185396Abstract: A device that uses electrical discharges/nonthermal plasmas in a gaseous medium to activate a fuel or fuel-oxidizer mixture to promote more effective and efficient combustion, in which a dielectric barrier discharge or silent discharge plasma is used to break up larger organic molecules (the fuel) into smaller ones that are more easily and completely combusted. The discharge also creates free radicals that promote more efficient combustion. The device is a cylindrical, coaxial (cylinder in a cylinder) dielectric barrier discharge/silent discharge plasma reactor. It includes two conducting electrodes, one or both of which are covered by a dielectric material. The electrodes are separated by a thin, gas-containing space. A high voltage is applied to the electrodes to create electric discharge streamers in the gas. The discharges are the source of the nonthermal plasma.Type: ApplicationFiled: March 21, 2003Publication date: September 23, 2004Applicant: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Louis A.

Patent number: 4317067Abstract: A discharge device (10) is disclosed which is capable of providing preionizing ultraviolet wave length photons to the area of a gap between the first (15) and second (35) electrodes of the device. The first electrode (15) includes a core (20) of dielectric material, a conductive plate (23) mounted on one surface of the core, and a conductive grid (26) mounted on an opposed surface of the core which faces the second electrode. The application of a negative voltage pulse to the grid (26), while the plate (23) is maintained at substantially ground potential, causes electrons to discharge between the conductors of the grid and the adjacent surface of the dielectric core, and, in doing so, generates photons having wavelengths in the ultraviolet range. The ultraviolet photons, which are emanated in a two dimensionally uniform pattern over the surface of the dielectric core adjacent the grid, cause ionization of the gas within the main discharge gap between the first and second electrodes.Type: GrantFiled: April 11, 1980Date of Patent: February 23, 1982Inventors: William A. Fitzsimmons, Louis A. Rosocha
