摘要： A method for monitoring non-rotating turbomachine parts includes the step of measuring displacement of at least one turbomachine part. A monitoring step monitors displacement of the turbomachine part with a non-contact type sensor. A collecting step collects data regarding the displacement of the turbomachine part. An analyzing step analyzes the data to determine if the displacement exceeds a predetermined threshold range. The non-contact type sensor may be attached to the turbomachine by a rod formed of a material having a low coefficient of thermal expansion, and a target may be attached to a stationary structure in close proximity to the non-contact type sensor.

摘要： 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.

摘要： Heating systems for a rotor in-situ in a turbomachine are provided. In contrast to conventional systems that merely heat from an external turbine casing, embodiments of the disclosure heat the rotor. In one embodiment, a heating system includes a heating element to heat a portion of an exterior surface of the rotor. In another embodiment, the heating system may include a heating element(s) at least partially positioned within the rotor, and the rotor including the heating system. Each embodiment may include a controller to control operation of the heating element(s).

摘要： 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.
