Abstract: A steam valve includes a housing defining a steam inlet and steam outlet in fluid communication with a valve cavity, and an annular valve seat disposed within the valve cavity. A control valve is configured to selectively engage the valve seat. The steam valve further includes a stop valve configured to selectively engage the valve seat. The steam valve includes a pressure seal head configured to receive the stop valve. The pressure seal head includes an elongated body having a bore extending longitudinally through the body; and a nose piece extending from an end of the elongated body. The nose piece has at least a tapered end portion and a bore extending longitudinally therethrough. The bore of the nose piece is longitudinally with the bore of the elongated body. The nose piece is formed of a first material which has greater erosion properties than a second material forming the elongated body.

Abstract: 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).

Abstract: 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.
