Definitions

  • Turbomachines such as steam turbines, are operated with a flow medium.
  • water vapor is used as the flow medium, which may have a temperature of over 600 ° C at a pressure of about 300 bar (30,000 kPa).
  • Such high temperatures and pressures make increased demands on the materials of the steam turbine.
  • the area of the steam inflow is subjected to high thermal and mechanical loads.
  • the object of the invention is to provide a steam supply which is suitable for high temperatures.
  • the expanded steam is usually brought in a reheater to a pressure of about 350 bar (35000 kPa) and as Reheater steam called.
  • This reheated steam can also be used as a cooling medium.
  • the outer pipe is connected to one another at a second location with the inner pipe.
  • the first component 23 comprises a first inner pipe 26. Furthermore, the first component 23 has a first outer pipe 27.
  • the second component 24 has a second inner pipe 28 and a second outer pipe 29. Between the first inner pipe 26 and the second inner pipe 28, an I-ring seal 30 can be arranged. Such an I-ring seal 30 may also be between the first outer pipe 27 and the second outer pipe 29 are arranged.
