Abstract: A casing half shell for a turbine system, a steam turbine system and related method are provided. The casing half shell includes a body having an open interior for enclosing parts of the turbine system; a first inlet in the body for delivering a first working fluid flow into the open interior in a first direction; and a second inlet in the body for delivering a second working fluid flow into the open interior in a second direction that is opposed to the first direction. A working fluid dam extends radially and axially in the body between the first inlet and the second inlet, the working fluid dam includes a stress-mitigating slot extending radially therein. A fill member may be mounted in the stress-mitigating slot to provide full functioning of the working fluid dam.

Abstract: A bolt tensioning assembly includes a bolt having a through-hole extending longitudinally through the bolt. A ram is inserted into the through-hole. A top cap is configured to be attached to a first end portion of the bolt. A load distributing member is configured to engage the ram at a location adjacent a second end portion of the bolt to distribute a force exerted thereon by the ram, and an actuator is connected to the top cap to exert a force on the ram to cause the ram to engage the load distributing member such that the bolt is placed under tensile stress.

Abstract: Systems and devices configured to reduce windage and mixing losses in a turbine by redirecting and/or aligning a direction of a leakage flow with the flowpath of the main flow of a turbine are disclosed. In one embodiment, a device includes: a base configured to connect to a diaphragm of a turbine; and a radial portion connected to the base and extending radially inboard from the base toward a rotor of the turbine, the radial portion oriented to adjust a direction of travel of a leakage flow of working fluid radially inboard at an angle complementary to a primary working fluid path of the turbine.

Abstract: A support system for assembling and shipping a steam turbine is provided that includes an annular support fixture configured to be coupled to a longitudinal end of a casing of the steam turbine. The annular support fixture includes a first protrusion that extends in an axial direction relative to a longitudinal axis of a rotor of the steam turbine between the rotor and the casing and that is configured to support the rotor in the radial direction. The annular support fixture includes a second protrusion, which extends in the radial direction toward a lateral surface of the rotor and which includes a surface configured to face the rotor in the axial direction. The support system includes a block configured to be disposed between the surface of the second protrusion and the rotor, such that the block blocks movement of the rotor in the axial direction during shipping of the steam turbine.

Abstract: A variable clearance mechanism for use in a turbine engine is provided that includes a stationary component, a plurality of articulating seal members coupled to the stationary component, and a biasing mechanism including an actuation ring. The variable clearance mechanism varies the position of stationary seal members to provide variable bucket tip clearance as a function of an operating condition of the turbine engine. The biasing mechanism is coupled to the plurality of articulating seal members for use in selectively translating the plurality of articulating seal members when the actuation ring is rotated circumferentially relative to the stationary component.
