摘要： A system controls net thrust of a steam turbine having a stepped rotating shaft. A first leak off line fluidly couples a first stage of a turbine section to a packing upstream of a stepped portion on the rotating shaft. A second leak off line fluidly couples a second stage of the turbine section that is subsequent to the first stage to a step area upstream of the stepped portion, and a connection line fluidly couples the first leak off line to the second leak off line. The lines include control valves such that a controller can actively control the net thrust by regulating thrust pressure on the stepped portion using steam from the first and second stages of the turbine section. The controller may also prevent damage to an active retractable seal using the control valves.

摘要： A standard for supporting a turbine rotor and a turbine shell includes a bearing block including a housing enclosing bearing surfaces engageable by the turbine rotor. Turbine shell-arm supports are located on opposite sides of the housing, the turbine shell-arm supports each having a horizontal and one or more vertical surfaces adapted to be engaged by support arms of a turbine shell enclosing at least a portion of the turbine. An internal cooling/heating circuit is arranged to simultaneously cool or heat the bearing block and the turbine shell-arm supports to thereby reduce differential thermal growth characteristics of the turbine rotor and turbine shell.

摘要： A seal assembly for sealing between a rotating component and a stationary component in a turbomachine. The seal assembly includes a plurality of radially inwardly projecting, axially spaced teeth extending from the stationary component, wherein at least one of the plurality of teeth has at least one axially extending hole therethrough. Axial flow of an operating fluid through the holes acts as an air-curtain to interrupt swirl flow in a seal cavity, therefore reducing steam force that could act to destabilize rotordynamics.
