  • Disabling circuit in steam turbines for shutting off saturated steam
    Patent number: 9726041
    Abstract: 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: Grant
    Filed: September 14, 2011
    Date of Patent: August 8, 2017
    Assignee: SIEMENS AKTIENGESELLSCHAFT
    Inventors: Henning Almstedt, Peter Dumstorff, Martin Kuhn, Thomas Müller, Rudolf Pötter, Norbert Thamm, Uwe Zander
  • Steam turbine in a three-shelled design
    Patent number: 9222370
    Abstract: A turbomachine including a rotor and an inner interior housing an outer interior housing and an exterior housing, wherein the turbomachine has a first flow and a second flow arranged opposite the first flow for a high-pressure blading or medium-pressure blading, wherein the inner interior housing is made of a higher quality material tan the outer interior housing and solely accommodates the high-pressure and medium-pressure inflow regions including the balance piston is provided.

  • Axially segmented guide vane mount for a gas turbine
    Patent number: 8870526
    Abstract: A stator blade carrier for a gas turbine is provided. The stator blade carrier includes a plurality of axial segments. At least one axial segment is designed as a tubular lattice structure. This allows a simpler design technically and a more flexible adaptation to the temperature profile present on the stator blade carrier to maintain operational safety.

  • Welded turbine shaft and method for producing said shaft
    Patent number: 7771166
    Abstract: The invention relates to a turbine shaft that is aligned in a longitudinal direction. Said shaft comprises a central region and two outer regions, which are fixed to the central region in the longitudinal direction. The central region is produced from a material with a higher heat resistance than the two outer regions.
