  • Patent number: 8162324
    Abstract: A method of assembling a turbomachine that includes a rotor and a stationary component is provided. The method includes coupling a housing to the stationary component using at least one biasing member, wherein the housing extending circumferentially about the rotor. The method also includes coupling at least one annular ring to the housing, and coupling a plurality of plate members to the housing such that the at least one annular ring extends from the housing towards the rotor and partially through the plurality of plate members.

  • Patent number: 7976026
    Abstract: A method and seal assembly for a rotary machine including a rotary component and a stationary component is provided. The method includes providing a seal housing including a front plate and a back plate that is spaced from the front plate such that a cavity is defined between the front plate and the back plate. The method also includes coupling a plurality of flexible compliant plates to at least one of the seal housing and the stationary component such that the compliant plates are spaced from the front plate and the back plate within the cavity, and coupling at least one projection to at least one of the seal housing and the compliant plates such that the at least one projection facilitates reducing flow through at least one of a first axial gap and a second axial gap that are defined between the seal housing and the compliant plates.

  • Publication number: 20080107525
    Abstract: A shaft seal reduces leakage between a rotating shaft and a stator. The shaft seal includes a plurality of plate members attached to the stator in facing relation. The plate members define a sealing ring between the stator shell and the rotating shaft. A thickness of the plate members tapers from thick to thin from a stator end to a rotating shaft end. In this manner, with the more tightly packed tips of the plate members, axial leakage is reduced by tapering the plate members so that the plate roots are thicker than the plate tips.

  • Publication number: 20040094631
    Abstract: A method of identifying a steam turbine includes defining a plurality of individual blocks that identify critical design features for a plurality of turbine sections, and separating each of the individual blocks with separators. Exemplary blocks are defined for, for example, turbine code type, rotational speed, maximum capability of structured design, nominal design conditions, high-pressure, intermediate-pressure and low-pressure block levels, high-pressure design type, low-pressure last stage bucket, and generator type. The identification number contains the minimum required set of criteria to identify a unique, structured turbine design. The number can be used to identify duplication as well as cost and design attributes that are significant for consistency across a power generation business.
