Abstract (en)
Steam turbine (2) comprises, a high pressure partial turbine (12), which is fluidically connected to a medium pressure partial turbine (14) and a common turbine shaft (6) is arranged to partial turbines. A cooling capacity (38) is provided, over which exhaust steam from the high pressure partial turbine can be supplied for cooling purposes into the medium pressure partial turbine. An independent claim is also included for method for cooling of a steam turbine.
