Abstract: A method for heating up a steam turbine or for keeping a steam turbine hot, which steam turbine has at least one pressure stage working at an initial pressure or intermediate pressure, at least one final pressure stage which is fluidically connected downstream of the pressure stage and works at a final pressure which is lower than the initial pressure or intermediate pressure, and at least one condenser which is connected downstream of the final pressure stage, wherein steam generated outside the steam turbine is introduced into the pressure stage. After flowing through the pressure stage and bypassing the final pressure stage, the steam is supplied directly to the condenser.

Abstract: A steam turbine having a cooling option, in which steam is taken from the flow channel, the steam cooling the thrust-compensating intermediate floor, being mixed with a small amount of live steam and being returned to the flow channel. A method cools the steam turbine, wherein steam is extracted from the high-pressure region and is fed to a space between the thrust-compensating partition wall and inner casing, wherein steam from the space between the thrust-compensating partition wall and the inner casing is fed via a first cross feedback passage to the high-pressure region.
