The airfoil core shape has a nominal profile substantially in accordance with Cartesian coordinate values of X, Y, and Z set forth in TABLE 1 where X and Y are distances in inches which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z in inches. The profile sections at the Z distances are joined smoothly with one another to form a complete airfoil core shape.

    摘要: A combined cycle power plant includes a first compressor that produces a compressed working fluid and a turbine downstream of the first compressor. The turbine includes stationary components and rotating components and produces an exhaust. A heat exchanger downstream of the turbine receives the exhaust from the turbine, and a second compressor downstream of the heat exchanger and upstream of the turbine receives the exhaust from the heat exchanger and provides a flow of exhaust to the turbine. A method for reducing oxygen emissions from a gas turbine includes flowing an exhaust from a turbine to a heat exchanger and removing heat from the exhaust. The method further includes increasing the pressure of the exhaust to produce a pressurized exhaust and flowing the pressurized exhaust back to the turbine to remove heat from the turbine.

    摘要: A power plant arrangement and method of operation are provided. The power plant arrangement comprises at lease one main air compressor and one or more gas turbine assemblies. Each assembly comprises a turbine combustor for mixing a portion of a compressed ambient gas flow with a portion of a recirculated low oxygen content gas flow and a fuel stream, and burning the combustible mixture to form the recirculated low oxygen content flow. The assembly further comprises a turbine compressor, fluidly connected to the turbine combustor, and connected to a turbine shaft that is arranged to be driven by rotation of a turbine. The assembly also comprises a recirculation loop for recirculating at least a portion of the recirculated low oxygen content gas flow from the turbine to the turbine compressor.

    摘要: Blade load path on a gas turbine disk can be diverted to provide a significant disk fatigue life benefit. A plurality of gas turbine blades are attachable to a gas turbine disk, where each of the gas turbine blades includes a blade dovetail engageable in a correspondingly-shaped dovetail slot in the gas turbine disk. In order to reduce gas turbine disk stress, an optimal material removal area is defined according to blade and/or disk geometry to maximize a balance between stress reduction on the gas turbine disk, a useful life of the gas turbine blade, and maintaining or improving the aeromechanical behavior of the gas turbine blade. Removing material from the material removal area effects the maximized balance.
