A coupling device for connecting a clutch to a turbine train, a turbine train having a clutch, and a method for connecting a clutch to a generator and to a turbine. The coupling device for connecting the clutch has a first coupling flange and a second coupling flange, wherein the first coupling flange and the second coupling flange each have at least one bore for accommodating a coupling bolt. The first coupling flange and the second coupling flange are centered in relation to each other by means of at least one coupling bolt, which is inserted into the bores in the first and in the second coupling flange.

A valve for a turbomachine, has a valve cone and a valve seat, the valve cone being configured such that it can be moved in a valve body with respect to the valve seat. The opening and closing of the valve being achieved by the use of process-internal media taking into account different geometries of the working chambers and the use of thermodynamically different state variables.

Valve for a turbomachine

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.

Steam turbine and method for operation of a steam turbine

The invention relates to a method and a device for cooling thermally stressed regions in a turbo machine which has a live-steam feed line (), an inflow region (), a housing () and an exhaust-steam region (), a flow medium flowing through the turbo machine () and leaving in the exhaust-steam region () during operation, part of the flow medium from the live-steam feed line () being passed to the exhaust-steam region () and cooled by means of a heat exchanger () before entry into the turbo machine () and entering the turbo machine () via the inflow region (), thermally stressed regions that are located in the inflow region () being cooled by the f low medium that has been cooled in this way.
