摘要： A pollutant destruction system connects a capacitive corona discharge chamber in a self-resonant circuit with an inductive element. Intermittent energizing signals are furnished from a power supply to induce corona discharges within the chamber, with the resonant circuit responding to the energizing signals by initiating additional corona discharges between energizing signals in a highly energy efficient operation. One or more discharge chambers can be provided in the resonant circuit, with each discharge chamber comprising a dielectric enclosure with a distributed electrode outside and an elongate electrode inside the enclosure. The inner electrode can extend either along the chamber axis, or along the inner chamber wall for better support and heat dissipation. The energizing pulse frequency can be controlled in various ways, such as in response to a termination of corona discharges, an increase in the pollutant concentration or an acceleration of an engine whose exhaust is being treated, or the pulses can be applied at a fixed rate.

摘要： A method for a regenerative heat exchanger for the treatment of pollutant-containing waste gases which are in a heat exchange with another medium. The heat exchanger includes stationary or rotating storage masses which are at least partially of catalytic material and to which a reduction agent is supplied from the hot side thereof. A penetration of the reduction agent into the flue gas flow can be prevented by supplying the reduction agent directly to the catalyst separately from the pollutant-containing waste gases and without coming into contact with the remaining heating surfaces. For this purpose, a nozzle arrangement having at least one arm and extending over the entire radius of the heat exchanger may be arranged in both hood sides of the heat exchanger.

摘要： A method and apparatus for the treatment of a waste gas containing dust and chemical contaminants are disclosed. The apparatus includes a combination of a cooling/dust-eliminating chamber and a chemical treatment chamber in a single container. The first mentioned chamber is provided with sprayers for the cooling liquid, a perpendicular bulkhead or pipes, a collecting plate for the cooling liquid and gas-dispersing pipes in a special configuration, so that the dust-liquid separation can be efficiently effected without badly affecting the chemical treatment of the gas. Thus, the apparatus can be minimized in size as a whole and made economically attractive.

摘要： A process and device for the treatment of fluid, such as flue gas. A moving bed reactor has several reaction chambers. The reaction chambers are located in parallel flow locations. A solid bulk material is located in the reaction chambers. The fluid flows through the reaction chambers in parallel, from bottom to top of each reaction chamber. As the fluid flows through the reaction chambers, the fluid interacts with the bulk material to alter the fluid. Specifically, the bulk material absorbs and/or acts as a catalyst to remove impurities from the fluid. Flow through each of the reaction chambers can be interrupted without interruption of flow through the other reaction chambers. Some of the bulk material in each reaction chamber can be removed, as a layer, from the bottom and a replacement amount can be added, as a layer to the top.

摘要： A two-stage flue gas treatment condensing heat exchanger system allows for flue gas to be passed into a two-stage housing at an inlet of the housing. The flue gas is channeled downwardly through a first stage of the housing having a first condensing heat exchanger which cools the flue gas. The flue gas is then upwardly channeled in the housing through a second stage having a second condensing heat exchanger which is located near an outlet. A collection section is located between the first stage and the second stage of the housing for collecting liquids, condensate, particulate and reaction product. Steam is injected into the housing at a plurality of locations for enhancing particulate removal.

摘要： A plant with a gas turbine such as a combined cycle power plant of a gas turbine cycle and a steam turbine cycle is provided with a nitrogen oxide removal device for removing NO.sub.x by injecting ammonia to an exhaust gas of the gas turbine. The device reduces NO.sub.x concentration to a certain value or less before the exhaust gas is released to the air. An ammonia flow amount is rapidly controlled such that a mole ratio of ammonia to NO.sub.x coincides with a set mole ratio value. The mole ratio is calculated from a predicted NO.sub.x concentration at an inlet of the nitrogen oxide removal device predicted by calculating operation conditions of the gas turbine, an ammonia flow amount value, and an exhaust gas flow amount. The set mole ratio value is calculated from a deviation of a measured NO.sub.x concentration value at an outlet of the nitrogen oxide removal device and a set NO.sub.x concentration value, and an amount of water injected to a combustor. Finally, a controlled system is stabilized in a state where a measured NO.sub.x concentration value coincides with the set NO.sub.x concentration value at a high speed.

摘要： In a method for cleaning polluted gas and/or cooling of hot gas, and a device for carrying out the method, the gas is contacted with finely divided liquid. The finely divided liquid is supplied in the form of essentially umbrella-shaped shells or essentially linear curtains, in a regular arrangement, distributed in two or more planes substantially perpendicular to the main flow direction of the gas. The finely divided liquid is supplied such that the gas is alternatively concentrated and spread by the impulse action exerted by the liquid on the gas in directions perpendicular to the main flow direction of the gas. The orthogonal distance between adjacent planes in which finely divided liquid is supplied, is so adjusted that no substantial equalization of the gas flow takes place between the planes. The supply of liquid in adjacent planes is so arranged that it, in a plane located downstream in the flow direction of the gas, takes place where the flowing gas has been concentrated by the impulse action of liquid supplied in the plane located immediately upstream.
