Patent number: 10415395Abstract: A method is disclosed for cooling a gas turbine having a turbine, wherein a rotor, which rotates about a machine axis, carries a plurality of rotating blades, which are mounted by blade roots and extend with their airfoils into a hot gas path of the gas turbine. The rotor is concentrically surrounded by a turbine vane carrier carrying a plurality of stationary vanes, whereby the rotating blades and the stationary vanes are arranged in alternating rows in axial direction. An extended lifetime with external cooling is achieved by providing first and second cooling systems for the turbine.Type: GrantFiled: May 13, 2016Date of Patent: September 17, 2019Assignee: Ansaldo Energia Switzerland AGInventors: Oliver Joseph Taheny, Sven Olmes, Armin Busekros, Carlos Simon-Delgado, Daniel Jemora, Christophe Simonet, Luca Alberti, Eugenio Rossi

Patent number: 10273976Abstract: An actively morphable vane includes a leading edge, a trailing edge downstream of the leading edge, a tip end, a hub end spaced radially outward from the tip end, a pressure side comprising a pressure surface, and a suction side comprising a suction surface. The pressure surface extends continuously between the tip end, the hub end, the leading edge, and the trailing edge. The suction side is positioned opposite of the pressure side and the suction surface extends continuously between the tip end, the hub end, the leading edge, and the trailing edge. The actively morphable stator vane also includes an actuator in mechanical communication with the tip end. The actuator is operable to selectively morph the actively morphable stator vane between a first configuration and a second configuration. The first configuration is optimized for a first operating condition, and the second configuration is optimized for a second operating condition.Type: GrantFiled: February 3, 2017Date of Patent: April 30, 2019Assignee: General Electric CompanyInventors: Daniel Jemora, Damir Novak, Hermann Nachtigall

Publication number: 20170226862Abstract: The present disclosure relates to a rotor for a gas turbine having a plurality of rotor disks arranged one behind the other in a rotor axis and connected to one another, where the geometrical form of the disks leads to the formation of cavities between adjacent disks. The rotor extends from a compressor part to a turbine part and has a central part between the compressor part and the turbine part, wherein the first turbine disk, the last compressor disk and the central part enclose a central cavity. A cooling system extends at least partially through the rotor with a central cooling section disposed between at least one inlet pipe and at least one outlet pipe, at least partially through the first turbine disk and/or the last compressor disk.Type: ApplicationFiled: February 9, 2017Publication date: August 10, 2017Applicant: ANSALDO ENERGIA SWITZERLAND AGInventors: Stefan BOELLER, Daniel JEMORA

Publication number: 20170138265Abstract: A gas turbine is disclosed which includes a compressor, a combustor downstream of the compressor, a turbine downstream of the combustor, a heat exchanger, a first cooling fluid system and a second cooling fluid system. The first and the second cooling fluid systems are each configured and arranged to extract a cooling fluid from the compressor and to cool a part of the gas turbine using the cooling fluid. The first and the second cooling fluid systems each extend from the compressor to the heat exchanger and from the heat exchanger to the part of the gas turbine to be cooled. The heat exchanger can exchange heat from the cooling fluid in the second cooling fluid system to the cooling fluid in the first cooling fluid system. A rotor cover with a heat exchanger and methods of operation are also described.Type: ApplicationFiled: November 14, 2016Publication date: May 18, 2017Applicant: Ansaldo Energia Switzerland AGInventors: Carlos Simon-Delgado, Oliver Joseph Taheny, Sven Olmes, Luca Alberti, Daniel Jemora

Publication number: 20160177833Abstract: Disclosed is an engine, the engine having a compressor, an expansion machine, and a shaft, the shaft having a direction of rotation. The engine includes a compressed fluid main flow path, a flow divider arranged at and fluidly connected to the compressed fluid main flow path, and a duct fluidly connecting the flow divider and components of the expansion machine. The duct is arranged such that, when the engine is operated, a fluid is guided through the duct from the flow divider towards the expansion machine components. A flow deflector device is arranged within a flow path and configured to deflect and thereby accelerate a flow therethrough directed form the flow divider towards the expansion machine components in a tangential direction, wherein the deflection can be effected into the shaft direction of rotation.Type: ApplicationFiled: December 22, 2015Publication date: June 23, 2016Applicant: General Electric Technology GmbHInventors: Carlos SIMON-DELGADO, Oliver Joseph TAHENY, Sven OLMES, Armin BUSEKROS, Luca ALBERTI, Daniel JEMORA, Eugenio ROSSI, Christophe SIMONET
