    摘要: A turbine casing has an inner casing and an outer casing which surrounds the inner casing to form an intermediate space. In order to avoid a casing distortion, a forced flow of a medium located within the intermediate space is provided. A method is also described which relates to avoiding a temperature based casing distortion during the shut-down of a turbine.

    摘要: Disclosed is a steam turbine comprising an exterior housing and an interior housing. The exterior housing and the interior housing are provided with a fresh steam supply duct. A rotor that encompasses several impeller blades and a thrust-compensating piston is rotably mounted within the interior housing. The interior housing is equipped with several guide blades that are disposed such that a flow duct comprising several blade stages, each of which comprises a series of impeller blades and a series of guide blades, is formed along a specific direction of flow. The interior housing is further equipped with a recirculation duct which is embodied as a pipe that communicates between a space located between the interior housing and the exterior housing and the flow duct downstream of a blade stage. The interior housing is additionally equipped with a supply duct that is configured as a pipe which communicates between the space located between the interior housing and the exterior housing and an antechamber of the thrust-compensating piston located between the thrust-compensating piston of the rotor and of the interior housing.
