Definitions

  • the outer inner casing is subjected to a vapor having a lower temperature and a lower pressure, so that the material of the outer inner casing must be less heat-resistant than the material of the inner inner casing.
  • the outer inner housing is formed of a less high-quality material.
  • an outer housing is arranged around the inner inner housing and the outer inner housing.
  • the sectional view through the turbomachine 1 shown essentially comprises an outer housing 2, an outer inner housing 3 arranged inside the outer housing 2 and an inner inner housing 4 arranged inside the outer inner housing 3.
  • the outer inner housing 3 is in this case formed with respect to the axis of rotation 6 about the inner inner housing 4. Outside the first flow region 8, the outer inner casing 3 is not arranged around the inner inner casing 4 relative to the axis of rotation 6.
  • the first flow region 8 comprises the flow channel up to the point at which the inner inner housing 4 stops.
  • a fluidic connection 11 is arranged at the transition region between the first flow region 8 and the second flow region 10. A relaxed steam from the flow channel 7 can thus flow through the fluidic connection 11 in a located between the inner inner housing 4 and the outer inner housing 3 cooling steam space 12.
