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.
Claims12
1-11. (canceled)
A steam turbine, comprising:
- a rotatably mounted rotor;
- an inner casing;
- a high-pressure flow duct arranged between the rotor and the inner casing;
- a second flow duct;
- and
- an inflow zone assigned to the second flow duct,
- wherein the rotor has a dummy piston,
- wherein the steam turbine has a dummy piston line,
- wherein the dummy piston line opens into a dummy piston prechamber,
- wherein the steam turbine has a wet steam line, which establishes a fluidic connection between a gap space and a first pressure space,
- wherein the gap space is arranged between the rotor and the inner casing, and
- wherein the dummy piston line is connected fluidically to the inflow zone.
