摘要： An apparatus and method for creating high temperature plasmas for enhanced chemical processing of gaseous fluids, toxic chemicals, and the like, at a wide range of pressures, especially at atmospheric and high pressures includes an electro-magnetic resonator cavity, preferably a reentrant cavity, and a wave guiding structure which connects an electro-magnetic source to the cavity. The cavity includes an intake port and an exhaust port, each having apertures in the conductive walls of the cavity sufficient for the intake of the gaseous fluids and for the discharge of the processed gaseous fluids. The apertures are sufficiently small to prevent the leakage of the electro-magnetic radiation from the cavity. Gaseous fluid flowing from the direction of the electro-magnetic source through the guiding wave structure and into the cavity acts on the plasma to push it away from the guiding wave structure and the electro-magnetic source. The gaseous fluid flow confines the high temperature plasma inside the cavity and allows complete chemical processing of the gaseous fluids at a wide range of pressures.

摘要： A method and apparatus for separating particulate matter from a gas stream wherein dirty gas is moved first through a corona discharge zone, such as that provided by a plurality of rod-like electrodes each having a sharp-edged corona producing ribbon-like formation extending axially therealong, and then is moved through a plurality of mechanical filters of the cartridge type, each comprising a perforated, cylindrical, metal outer shell and an inner filter medium of foraminous dielectric material such as pleated paper. Each cartridge is closed at one end and open at the other from which cleaned gas flows out axially. The electrodes are located circumferentially of the filters with the filter and electrode longitudinal axes being substantially parallel. The conductive outer shells of the filter elements are connected to an electrical reference such as ground and the electrodes are connected to a relatively high electrical potential in a manner generating corona discharge between the electrode formations and the filter element shells. Collected particulate material in the filter media and on the shells is removed by introducing a controlled quantity of high pressure gas at predetermined times and at a location to induce a substantial flow of gas through the apparatus in a reverse direction.

摘要： A catalytic reactor (10) for oxidizing elemental mercury contained in flue gas is provided. The catalyst reactor (10) comprises within a flue gas conduit a perforated corona discharge plate (30a, b) having a plurality of through openings (33) and a plurality of projecting corona discharge electrodes (31); a perforated electrode plate (40a, b, c) having a plurality of through openings (43) axially aligned with the through openings (33) of the perforated corona discharge plate (30a, b) displaced from and opposing the tips of the corona discharge electrodes (31); and a catalyst member (60a, b, c, d) overlaying that face of the perforated electrode plate (40a, b, c) opposing the tips of the corona discharge electrodes (31). A uniformly distributed corona discharge plasma (1000) is intermittently generated between the plurality of corona discharge electrode tips (31) and the catalyst member (60a, b, c, d) when a stream of flue gas is passed through the conduit. During those periods when corona discharge (1000) is not being generated, the catalyst molecules of the catalyst member (60a, b, c, d) adsorb mercury vapor contained in the passing flue gas. During those periods when corona discharge (1000) is being generated, ions and active radicals contained in the generated corona discharge plasma (1000) desorb the mercury from the catalyst molecules of the catalyst member (60a, b, c, d), oxidizing the mercury in virtually simultaneous manner. The desorption process regenerates and activates the catalyst member molecules.

摘要： The present invention pertains to a method for nitrogen oxide reduction and flue gas reheating wherein a catalyst surface is heated to an operating temperature to facilitate a catalytic reduction reaction in the presence of relatively cool flue gas. To avoid conventional complication the catalytic reduction reaction is performed downstream of both particulate control operations and desulfurization procedures. That is, the catalyst surface itself is placed just before the stack. The method of the present invention reheats the flue gas prior to its exit into the atmosphere.
