Abstract: The invention relates to a method for regulating a steam turbine (1), according to which steam is fed to the steam turbine (1) via at least three valves, whereby one of the valves is regulated as a regulating valve (9, 11), and at least two valves are controlled as control valves (13, 15).

Abstract: A steam turbine has a turbine shaft directed along a turbine axis. A plurality of turbine stages, each include a guide-blade structure and a moving-blade configuration located axially downstream of the guide-blade structure. The guide-blade structure and the moving-blade configuration are provided along the turbine shaft. Each stage has an average reaction degree achievable between 5% and 70%. The reaction degree of at least two turbine stages is of different values.

Abstract: A turbomachine, especially a steam turbine, includes a casing, an inflow region formed at least in part by the casing for guiding working fluid, a feed for a cooling fluid, a rotating-blade carrier disposed in the casing and extending along a principal axis, and a shielding element disposed in the inflow region for shielding the rotating-blade carrier from the working fluid. The shielding element is attached to the casing by a mounting and the feed is guided through the mounting. A method is also provided for cooling one or more components of a turbomachine adjoining an inflow region for a hot working gas.

Abstract: A turbine plant, in particular a steam-turbine plant, includes at least two turbine sections, each having a turbine rotor extending along a main axis and an inner casing accommodating guide blades. At least one inner casing is displaceable in axial direction and a thermally expanding thrust element is provided for an axial displacement. The trust element has first and second expansion components connected to one another by a coupling component. The coupling component mechanically and/or hydraulically produces an axial displacement of the second expansion component which is greater than a thermal expansion and/or axial displacement of the first expansion component. A thrust element for reducing different axial expansions between two components expandable independently of one another along a main axis, is also provided.

Abstract: A structural member is provided for an exhaust-gas connection of a turbomachine, in particular a steam turbine, and a turbomachine bearing disposed in the exhaust-gas connection. The structural member is cast in one piece and has a connection part and/or a bearing part for accommodating the bearing as well as a supporting arm configuration with at least one supporting arm. A pipe conduit which is cast into the structural member leads through a connection part, a supporting arm and a bearing part. A set of at least two such structural members form an exhaust-gas connection and a frame for the bearing of the turbomachine.

Abstract: A turbine shaft, in particular for a combined high-pressure/intermediate-pressure steam turbine accommodated in a common casing and a method of cooling a turbine shaft of a steam turbine. The turbine shaft has a cooling line in its interior for guiding cooling steam. The cooling line is connected on one side to an outflow line and on the other side to an inflow line. Steam cooling of the turbine shaft of a combined high-pressure/intermediate-pressure steam turbine can thereby be achieved by feeding steam from the high-pressure part through the inflow line to the intermediate-pressure part and through the outflow line.

Abstract: A device for discharging a liquid lubricant from a bearing configuration for a shaft which rotates around an axis, in particular for a steam turbine. The bearing configuration has a bearing, upon which the lubricant acts and which mounts the shaft, at least one seal, which is adjacent to the bearing and encircles the shaft, and a collecting chamber which is assigned to a first end of the bearing and encircles the shaft. The lubricant that escapes at the first end can be intercepted and channeled away by way of the collecting chamber. A lubricant sump chamber is provided geodetically beneath the bearing and is connected to a lubricant outflow. The collecting chamber has a deflection duct that extends through the lubricant sump chamber and is intended for channeling away the lubricant into the lubricant outflow. There is also taught a process for discharging a liquid lubricant from the bearing configuration.

Abstract: A shaft-turning device includes a driving element in the form of a hydraulic motor having a first pressure fluid inflow line, and an element for connection with a shaft to be turned in the form of a clutch having a second pressure fluid inflow line communicating with the first pressure fluid inflow line. The clutch includes locking elements being hydraulically forced counter to a spring force.

Abstract: An assembly for the leakage-free removal of bearing oil from sliding bearings for rotating shafts of high-speed machines, includes a sliding bearing axially divided into bearing cups, contactless shaft seals near bearing end surface preventing escape to the surroundings of bearing oil fed to surfaces of the sliding bearing, an annular oil collecting canal disposed at least at one side of the sliding bearing between a shaft seal and a bearing end surface having an outer peripheral wall with an arcuate cutout formed therein with a slot-shaped opening arc defining an outlet opening through which the collecting canal discharges an oil flow, the opening arc covering a circumferential angular range of the shaft extending at least from the geodetically lowest point of the outer contour of the collecting canal at most to a position of the outer contour defined by the parting line of the cups as seen in shaft rotation direction, an oil collecting box with an oil flow space and an inlet opening matched to the outlet cr
