Abstract: A power generation system includes: a first gas turbine system including a first turbine component, a first integral compressor and a first combustor to which air from the first integral compressor and fuel are supplied, the first combustor arranged to supply hot combustion gases to the first turbine component, and the first integral compressor having a flow capacity greater than an intake capacity of the first combustor and/or the first turbine component, creating an excess air flow. A second gas turbine system may include similar components to the first except but without excess capacity in its compressor. A control valve system controls flow of the excess air flow from the first gas turbine system to the second gas turbine system. A supplemental compressor may be coupled to the excess air flow path for augmenting the excess air flow with additional air.

Abstract: A power generation system includes a gas turbine system including a turbine component, an integral compressor and a combustor to which air from the integral compressor and fuel are supplied, the combustor arranged to supply hot combustion gases to the turbine component, and the integral compressor having a flow capacity greater than an intake capacity of at least one of the combustor and the turbine component, creating an excess air flow. A first control valve system controls flow of the excess air flow along an excess air flow path to an exhaust of the turbine component. A selective catalytic reduction (SCR) unit may be coupled to an exhaust of the turbine component, the SCR unit receiving the exhaust and the excess air flow. An eductor may be positioned in the excess air flow path for using the excess air flow as a motive force to augment the excess air flow with additional air, creating an augmented excess air flow.

Abstract: Disclosed herein are systems and methods for protecting a surface from corrosive pollutants. A method includes detecting airborne corrosive pollutants proximate to a surface using at least one sensor adapted to detect a concentration of the airborne corrosive pollutants and/or one or more types of airborne corrosive pollutants, the concentration of the airborne corrosive pollutants being an instantaneous concentration value or a time-weighted-integrated concentration value; selecting a fluid to deliver to at least a portion of the surface based upon a predetermined type and/or concentration of the airborne corrosive pollutants detected by the at least one sensor; and initiating a fluid treatment to deliver the selected fluid such that the selected fluid contacts the at least a portion of the surface.

Abstract: A method for measuring a lower heating value of a gaseous fuel. The method includes mixing a gaseous fuel with air to provide a combustible air-fuel mixture. The air-fuel mixture is directed to flow across a flow surface of a first micro-hotplate maintained at a constant temperature. A change in power required to maintain a constant temperature of the first micro-hotplate flow surface due to a convective and conductive heat transfer from the first micro-hotplate flow surface to the air-fuel mixture is measured. The air-fuel mixture is directed to flow across a flow surface of a second micro-hotplate maintained at a constant temperature. The air-fuel mixture is combusted as the air-fuel mixture flows across the second micro-hotplate flow surface. A change in power required to maintain a constant temperature of the second micro-hotplate flow surface due to the combustion of the air-fuel mixture is measured.

Abstract: A sensor for measuring Wobbe index of a fuel is provided. The sensor includes a substrate and a diaphragm layer. The diaphragm layer includes a first layer having at least one heating element configured to sense energy content in a fuel, wherein the heating element includes a doped poly-silicon carbide that is disposed on the substrate. The diaphragm layer also includes a second layer including an undoped poly-silicon carbide layer configured to prevent oxidation of the first layer. The sensor further includes a sensing layer having a catalyst suspended in a support structure. The sensor also includes a cavity formed under the diaphragm layer and is configured to provide thermal isolation of the heating element.
