Abstract
A turbine shaft, in particular for a combined high-pressure/intermediate-pressure steam turbine accommodated in a common casing and a method of cooling a turbine shaft of a steam turbine. The turbine shaft has a cooling line in its interior for guiding cooling steam. The cooling line is connected on one side to an outflow line and on the other side to an inflow line. Steam cooling of the turbine shaft of a combined high-pressure/intermediate-pressure steam turbine can thereby be achieved by feeding steam from the high-pressure part through the inflow line to the intermediate-pressure part and through the outflow line.
