Abstract
A turbine shaft for a steam turbine, in particular having a high-pressure and an intermediate-pressure turbine section. The turbine shaft has in its interior a cooling line for passing cooling steam. The cooling line is connected, on the one hand, to an outflow line and, on the other hand, to an inflow line. In this way, steam cooling of the turbine shaft can be achieved by feeding steam from the high-pressure turbine section via the inflow line to the intermediate-pressure turbine section through the outflow line. The invention also relates to a method of cooling a turbine shaft of a steam turbine.
