Patent number: 10167742Abstract: A steam cycle for a power station, and to a method for operating, in particular for starting, a steam cycle. The steam cycle has a high-pressure turbine, a condenser and a steam generator. The steam generator is connected to the high-pressure turbine via a first line. Live steam quick-closing valves and live steam regulating valves for supplying the high-pressure turbine are arranged in the direction of the steam flow between the steam generator and the high-pressure turbine. A starting line is arranged downstream of the high-pressure turbine in the direction of the steam flow, the starting line connecting a waste steam region downstream of the high-pressure turbine with the condenser. At least one regulator regulates a closing of a starting valve for sealing the starting line, and an opening of the live steam valve, depending on the rotational speed, a temperature and load state of the high-pressure turbine.Type: GrantFiled: April 16, 2015Date of Patent: January 1, 2019Assignee: Siemens AktiengesellschaftInventors: Bernd Leu, Martin Ophey, Klaus Rothe, David Veltmann, Kai Brune, Matthias Heue, Rudolf Pötter, Michael Schütz

Patent number: 9726041Abstract: A cooling option for a steam turbine is provided, wherein the steam turbine includes a high-pressure zone and a medium-pressure zone, wherein the saturated steam streaming out of the high-pressure zone is discharged via a saturated steam conduit to a first pressure chamber in a second flow channel of the medium-pressure zone and thus the possibility of the saturated steam causing damage by corrosion and erosion in the high-pressure zone is prevented.Type: GrantFiled: September 14, 2011Date of Patent: August 8, 2017Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Henning Almstedt, Peter Dumstorff, Martin Kuhn, Thomas Müller, Rudolf Pötter, Norbert Thamm, Uwe Zander

Patent number: 9556752Abstract: A steam turbine system including a steam turbine is provided, the steam turbine having an incoming and an outgoing steam side, and a turbine housing with a feed-through for a turbine shaft with a seal, whereby a fluid flow through the feed-through can be minimized, and a steam conducting system to the seal is present. The steam turbine includes a first sub-section a second sub-section, and a connecting line to a region of low pressure between two sub-sections. A steam supply through the steam conducting system is possible for starting up the steam turbine such that a steam flow from the outgoing steam side to the connecting line to the region of low pressure is possible, an incoming steam feed line has a shut-off that can be controlled such that a steam flow from the incoming steam side to the connecting line to the region of low pressure.Type: GrantFiled: March 27, 2013Date of Patent: January 31, 2017Assignee: SIEMENS AKTIENGESELLSCHAFTInventor: Rudolf Potter
