Abstract: An apparatus for a gas turbine engine includes an airfoil, a metering opening for metering a cooling fluid, a cutback slot configured to deliver the cooling fluid from the metering opening, and a cooling hole. The airfoil defines a trailing edge, opposite first and second faces, and a mean camber line. The cutback slot is defined along the first face of the airfoil adjacent to the trailing edge and offset from the mean camber line of the airfoil. The cooling hole has an outlet that is located at the trailing edge and substantially aligned with the mean camber line of the airfoil. The cooling hole delivers a portion of the cooling fluid from the metering opening.

Abstract: A power plant is provided which includes a gas turbine having a compressor for producing compressed air and a combustor for combusting the compressed air with a combustible fuel to produce a heated combustion gas. The power plant also includes a heat recovery steam generator for generating a flow of steam from an exhaust of the gas turbine and a steam turbine for expanding the flow of steam from the heat recovery steam generator. The steam turbine has a rotor having a rotor bore disposed axially therein. The power plant also includes a conduit for directing at least a portion of the compressed air or at least a portion of the heated combustion gas from the gas turbine to the rotor bore of the steam turbine, wherein the compressed air or the heated combustion gas may warm the rotor bore of the steam turbine.

Abstract: A portion of the exhaust generated by a turbomachine is recirculated through an inlet portion by an exhaust gas recirculation system. The system reduces the level of Sulfur Oxides and other constituents within the exhaust before the exhaust is recirculated. The system may utilize sea water, fresh water, or combinations thereof; as part of a scrubbing process to reduce the Sulfur Oxides and other constituents.
