Definitions

  • the cooling channels are advantageously comparative designed and extended large-area cooling of the housing wall viewed in the longitudinal direction of the rotor a certain minimum length.
  • the outline of the case essentially following, the cooling channels are therefore expedient aligned essentially in the longitudinal direction of the rotor.
  • FIG. 1 shows a schematic representation of a steam turbine 1, as in the prior art according to US 6,102,654 is described.
  • This has one rotatable on an axis 2 arranged rotor 3 with a number of blades designated rotor blades 4. These are in one stationary housing 5 arranged with a guide blading 6.
  • the rotor 3 is on the rotor blades 4 by the Inflow region 7 driven working medium 8 driven.
  • a cooling medium 10 to the working medium 8.
  • the cooling medium 10 cools exclusively by flow a first guide vane ring 11 of the stationary guide blading and a shielding plate 12.
  • FIG. 2 shows a schematic representation of a Steam turbine 20 according to a particularly preferred embodiment the invention.
  • the steam turbine 20 has a rotor 21 with a number of rotor or arranged thereon Blades 22 on which is rotatable in a housing shell 23 is supported with a number of guide vanes 24.
  • the steam turbine 20 with the rotor 21 and the casing jacket 23 extends itself along an axial extent Axis 25.
  • the rotatable blades 22 grip like Fingers in spaces between the stationary guide vanes 24th
  • sealing tips in the area of Turned joint 82 or adjacent to the blade feet, d. H. be made from solid, or sealing tapes be caulked. What turns out to be beneficial can, depending on the strength and manufacturing requirements of the Material and construction specified in detail become.
