Publication number: 20160290160Abstract: A turbomachine includes an inner housing which radially defines the flow channel of the turbomachine. A thermal barrier coating is arranged about the inner housing. The thermal barrier coating of the inner housing is made of microporous plastic coating which can be added to hollow spheres made of different materials and have different sizes. A method for applying a thermal barrier coating to the inner casing of a turbomachine includes preparing a material having a base material which has a microporous plastic; coating the outside of the wall of the inner casing by applying the base material to the inner casing; and curing the applied material, thus forming the thermal barrier coating.Type: ApplicationFiled: September 18, 2014Publication date: October 6, 2016Applicant: Siemens AktiengesellschaftInventors: Manuel ETTLER, Bora KOCDEMIR, Alexander LITINSKY, Andrey MASHKIN, Dieter MINNINGER, Adam ZIMMERMANN

Patent number: 9074490Abstract: A gas turbine including a plurality of hook elements disposed one inside the other and designed substantially in the form of hollow cones or hollow cylinders, and including a stator blade support, is intended to enable an especially high efficiency while maintaining the greatest possible operating safety and operating life. To this end, at least one of the hook elements or the stator blade support has a substantially elliptical cross-sectional contour.Type: GrantFiled: September 15, 2009Date of Patent: July 7, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Francois Benkler, Tobias Buchal, Andreas Böttcher, Martin Hartmann, Patricia Hülsmeier, Uwe Kahlstorf, Ekkehard Maldfeld, Dieter Minninger, Michael Neubauer, Peter Schröder, Rostislav Teteruk, Vyacheslav Veitsman

Patent number: 9057281Abstract: An axial turbomachine including a rotor-blade cascade is provided. The turbomachine includes a casing in which the cascade is installed and a guide-blade carrier which encloses the cascade and is integrated into the inner side of the housing. The guide-blade carrier is arranged immediately adjacently to the blade tips faulting a radial gap, wherein the guide-blade carrier is mounted in the housing, such that it may be displaced parallel to the axis of the axial turbomachine, and includes an adjusting ring which is supported on contact surfaces on the housing and guide-blade carrier and may be rotated about the axis, wherein the contact surfaces of the adjusting ring and of the housing and/or of the guide-blade carrier are set with respect to a plane perpendicular to the axis, so that, when the adjusting ring is rotated about the axis, the guide-blade carrier is displaced axially by the adjusting ring.Type: GrantFiled: March 22, 2010Date of Patent: June 16, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Francois Benkler, Andreas Böttcher, Uwe Kahlstorf, Torsten Matthias, Dieter Minninger, Oliver Schneider, Peter Schröder, Vyacheslav Veitsman

Patent number: 8635876Abstract: Disclosed is a gas turbine for a thermal power plant, especially a gas turbine, comprising a rotatable rotor and a duct which can be penetrated by a gas and in which turbine blades for driving the rotor are disposed. The inventive gas turbine is characterized by a blocking device which at least partially prevents the gas from penetrating the duct in a closed position.Type: GrantFiled: February 28, 2007Date of Patent: January 28, 2014Assignee: Siemens AktiengesellschaftInventors: Hajrudin Ceric, Stefan Dahlke, Uwe Gruschka, Matthias Heue, Martin Lenze, Thomas Matern, Dieter Minninger, Axel Schaberg, Stephan Schmidt, Steffen Skreba, Bernd Stöcker, Volker Vosberg, Roger Waldinger

Patent number: 8336315Abstract: A gas turbine, comprising a turbine and a compressor provided with a compressor housing, and to a method for the operation thereof. The compressor is tapped in order to cool the turbine by means of at least one tap line for removing compressed or partially compressed air. The tap line comprises a locking device, particularly a valve, in order to regulate the outflow of tapped air and thus the cooling of the housing.Type: GrantFiled: January 31, 2005Date of Patent: December 25, 2012Assignee: Siemens AktiengesellschaftInventors: Holger Bauer, Bernhard Küsters, Dieter Minninger, Marc Mittelbach, Andreas Peters, Stephan Schmidt, Steffen Skreba, Bernd Stöcker

Patent number: 7909565Abstract: The invention relates to a turbo-machine, in particular to a gas turbine and to a method for accelerating a temperature modification of a rotor shaft rotationally mounted in turbo-machine. The aim of invention is to develop a device and a method for the turbo-machine making it possible to reduce the size of a radial split of the turbo-machine in order to obtain greater degree of efficiency. The inventive turbo-machine comprises a rotor rotationally mounted in the case of the turbo-machine, a feeding channel embodied in the rotor for introducing a fluid and an outlet channel embodied in the rotor for removing fluid. An inlet orifice of the feeding channel is disposed further inside than the outlet orifice of the outlet channel, and arrangement influencing a liquid flow is formed of an actuating device dependent on centrifugal force. Methods for cooling the rotor only by decelerating the gas turbine and for heating the turbo-machine rotor by heating fluid flowing there-through are also disclosed.Type: GrantFiled: April 6, 2009Date of Patent: March 22, 2011Assignee: Siemens AktiengesellschaftInventor: Dieter Minninger

Patent number: 7766611Abstract: The invention relates a method for improving the hot-starting behavior of a turbomachine. By virtue of the setting of a radial gap formed between a brushing edge of a blade profile and a guide face lying opposite this, in which setting a guide ring forming the guide face can be acted upon with a coolant, the hot-starting behavior can be improved, in that the guide ring is cooled before the start of the machine.Type: GrantFiled: April 28, 2006Date of Patent: August 3, 2010Assignee: Siemens AktiengesellschaftInventors: Tobias Buchal, Gerhard Hülsemann, Mirko Milazar, Dieter Minninger, Michael Neubauer, Harald Nimptsch, Heinrich Pütz, Kang Qian, Arnd Reichert, Volker Vosberg
