Abstract

See full text

A turbomachine, in particular a steam turbine, has a shield and a coolant supply which causes cold intermediate superheater steam to flow onto the rotor, wherein additionally supply holes are arranged in the shield, which holes bring part of the hot inflow steam into the cooling region between the shield and the rotor, in order to thus improve mixing so as to raise the temperature of the rotor at this thermally loaded point, such that in the event of a fault (e.g., failure of the coolant line) the resulting change in temperature is moderate.
