Between a rotor (12) and an inner casing (IC) (11) there is a steam channel (SC) (14) containing a multistage structure of turbine vanes (16) fastened on the IC and of turbine vanes (17) fastened on the rotor. Tension from hot steam out of an incoming stream (15) is released under a working output. Plate-shaped protective shields (18-20) in the SC are parallel and near to the rotor surface. |
