Abstract

A method and a device are for cooling the inflow area of the shaft of a steam turbine. According to the method and device, a partial mass flow m1 is branched off upstream of a feed device that supplies the steam to the team turbine. The partial mass flow is cooled and then guided to the feed device, from where it is supplied to the steam turbine together with the remaining mass flow m2. The method and device allow for a simplified control and design of the turbine.
