1-10. (canceled)
A turbomachine, comprising:
- a rotor mounted rotatably about an axis of rotation;
- an internal inner casing arranged around the rotor;
- an external inner casing;
- and
- an outer casing being arranged around the internal inner casing and the external inner casing,
- wherein the turbomachine includes a first flow designed for high-pressure steam and a second flow designed for medium-pressure steam, the second flow being oriented opposite to the first flow, the first flow having a high-pressure inflow region and the second flow a medium-pressure inflow region,
- wherein the internal inner casing is arranged around the high-pressure inflow region and the medium-pressure inflow region,
- wherein the cooling steam flow line is connected fluidically to the second flow,
- wherein the first flow has a high-pressure outflow region and the second flow a medium-pressure outflow region, and
- wherein the external inner casing extends from the high-pressure outflow region as far as the medium-pressure outflow region.
