摘要： A thermally-activated flow clearance reduction for a steam turbine is disclosed. In one embodiment a gap closure component is located about a rotary component and a stationary component of the steam turbine. A temperature differential activates the gap closure component to seal or reduce the radial clearance of the steam flow path between the rotary component and the stationary component.

摘要： A steam turbine includes a rotor having a plurality of early stages and a stator portion surrounding a portion of the rotor and arranged such that a leakage region exists between the stator portion and the rotor and having a cooling steam channel that passes cooling steam from one portion of the stator portion to the leakage region. The turbine also includes at least one cooling steam transmission channel axially displaced about the rotor that receives the cooling steam from the leakage region and provides it to at least a portion of the early stages.

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.
