摘要： An apparatus for lifting an inner casing of a turbine includes a base, an arm, a guide roller, and an adjustment system. The arm has a first end and a second end, and is pivotally connected to the base intermediate the first end and the second end. The guide roller is operatively coupled to the first end of the arm to rotatably engage an exterior surface of the inner casing, and an adjustment system extending from the base and engaging the arm to change an angular position of the arm relative to the base and adjust a position of the guide roller relative to the exterior surface of the inner casing.

摘要： A system includes a turbomachine rotor having a shaft and turbomachine blades coupled to the shaft. The system also includes a turbomachine stator having a shroud surrounding the turbomachine blades of the turbomachine rotor. Further, the system includes a cooling channel having at least a first portion of the cooling channel extending upstream of a final stage of a compressor of the system, where the cooling channel is configured to receive cooled compressed air from the compressor and direct the cooled compressed air adjacent to the turbomachine rotor to reduce thermal expansion and/or axial displacement of the turbomachine rotor.

摘要： A system and process for restarting a turbomachine includes a shutdown cooldown protection process implemented by a plant level control system or direct control system of the turbomachine. The system and process for restarting ensure rotating components are cooled as expected prior to a unit restart. This system and process for restarting will lockout an ability to restart if an improper cooldown of rotating components is detected. If this lockout is enabled, delaying restart for the rotating components to cool naturally is needed, or the operator could decide to force cool the components.

摘要： A system for reducing leakage between static and rotating components within a turbine includes a static structure that is disposed radially outward from a tip of a rotating component. The static structure includes a seal assembly slot formed therein. A seal assembly includes a support block that is disposed within the seal assembly slot. A sealing material is disposed along a bottom portion of the support block and a tip slot is formed within the sealing material. The support block includes a forward portion that is slideably engaged with a forward inner surface of the seal assembly slot and an aft portion that is slideably engaged with an aft inner surface of the seal assembly slot. The system further includes a spring that extends axially between an aft wall of the seal assembly slot and an aft wall of the support block.

摘要： A gas turbine engine is disclosed having a turbine, one or more hydrocarbon gas combustors, and a compressor. The compressor has a rotor assembly with one or more rotor blade rows extending radially outward from an inner wheel disk. The compressor also has a stator assembly with one or more stator vane rows extending radially inward from an inner casing and positioned between adjacent rotor blade rows. The inner casing extends circumferentially around the rotor assembly and is constructed from at least one low-alpha metal alloy.

摘要： An article of manufacture includes a first member configured to be attached to a first support structure, a second member configured to be attached to the first member, and an externally threaded dowel configured to engage an internally threaded hole in the second member. The externally threaded member is also configured to contact the first member. Rotation of the externally threaded dowel adjusts a distance spanned by the first member and second member.
