Abstract (en)
[origin: EP1911933A1] The turbine (1) has a housing (39) provided with a feedthrough (20) for feeding an external cooling agent (21), and a rotor (5) that is partly formed in a hollow shape. The rotor includes a supply line (23) for feeding the external cooling agent into a hollow space (22) of the rotor via rotor cooling lines (24). The supply line is arranged adjacent to a balance piston (4). The rotor includes rotor blades allowing the flow of the cooling agent. The rotor blades are cooled by film cooling.
