    摘要: A steam generator coupled in flow communication downstream from a combustion device that produces a flow of exhaust gases includes a heating device configured to heat the exhaust gases that include oxides of nitrogen (NOx), and an oxidation catalyst coupled downstream from the heating device. The oxidation catalyst facilitates reducing an amount of NOx in the exhaust gases channeled into the oxidation catalyst at a first temperature that is less than a thermal regeneration temperature for a catalytic material and at a second temperature that is approximately equal to at least the thermal regeneration temperature such that the catalytic material is simultaneously regenerated.

    摘要: A method and system for controlling a temperature of an exhaust gas being introduced to a catalyst is provided. Using an adjustable flow controller, an adjustable amount of tempering fluid is provided to the exhaust gas prior to the exhaust gas proceeding to the catalyst. A sensor senses a parameter indicative of a temperature of the exhaust gas being introduced to the catalyst. A computer processor uses a relationship to relate the parameter to an adjustment of the adjustable flow controller that will adjust the amount of tempering fluid provided to the exhaust gas and change the temperature of the exhaust gas being introduced to the catalyst toward a target temperature. Adjustment of the adjustable flow controller is initiated by the computer processor to change the flow of the tempering fluid, and the relationship between the parameter and the adjustment of the adjustable flow controller is updated.

    摘要: Methods and systems are provided for reducing NOx emissions from a gas stream produced by a production source. The method may comprise oxidizing a substantial portion of NO gas present in the gas stream by contacting the gas stream with an oxidation catalyst to yield higher order NxOy molecules; and thereafter removing higher order NxOy molecules from the gas stream by solvent absorption or reaction. The system may comprise a gas production source configured to produce a gas stream comprising NOx; an oxidation catalyst positioned downstream of the gas production source, wherein the oxidation catalyst is configured to oxidize NO gas molecules in the gas stream to yield higher order NxOy molecules; and a removal device positioned downstream of the oxidation catalyst configured to remove higher order NxOy molecules from the gas stream by solvent absorption or reaction.

    摘要: A combustor assembly for a turbine engine includes a fuel nozzle located at an upstream end of the combustor assembly. The fuel nozzle includes both a fuel delivery passageway and a purge air passageway. The purge air passageway conveys a flow of purge air to cool the fuel nozzle. The combustor assembly also includes a combustion product return line that conveys a flow of combustion products from a position downstream of a combustion zone of the combustor back to the fuel nozzle. The combustion products are mixed with purge air, and the mixture is delivered into a combustion zone located just downstream of the fuel nozzle. The addition of the combustion products into the purge air reduces the amount of oxygen in mixed flow, which helps to reduce the generation of undesirable nitrogen oxide combustion byproducts. Also, the greater heat of the combustion products helps to increase the temperature of the mixture, which helps to maintain the stability of a pilot flame fed by the mixture.

    摘要: A system and method for reducing combustion dynamics includes first and second combustors arranged about an axis, and each combustor includes a plurality of tubes that extend axially through at least a portion of the combustor and a combustion chamber downstream from the plurality of tubes. A fuel injector extends through each tube to provide fluid communication into each tube at a fourth axial distance from the combustion chamber. The fourth axial distance in the first combustor is different than the fourth axial distance in the second combustor.
