| 20080265514 | Methods and apparatus to facilitate sealing in rotary machines - A method and seal assembly for sealing a rotary machine including a rotary component and a stationary component is provided. The method includes providing a plurality of flexible leaf plates in an opening defined between a pair of spaced walls that include an adjustable front wall and an adjustable back wall that is opposed to the front wall. The method also includes adjusting a width of the opening by axially adjusting at least one of the front and back walls with respect to a central rotational axis of the rotary component. | 10-30-2008 |
| 20090104028 | METHOD AND APPARATUS FOR DISTRIBUTING FLUID INTO A TURBOMACHINE - An apparatus for distributing a fluid in a gas flow path inside a turbomachine, comprising: a device for introducing the fluid into the gas flow path; and wherein the device is positioned within the gas flow path. A method for installing an apparatus that will distribute a fluid in a gas flow path inside a turbomachine, the method comprising: machining a casing groove along an inner surface of a casing; machining at least one port into the casing that is in fluid communication with the casing groove; machining an internal cavity in at least one stator blade that is in fluid communication with the casing groove; machining at least one orifice, that is in fluid communication with the internal cavity, on an orifice surface of the stator blade; and coupling a fluid supply to the at least one port. | 04-23-2009 |
| 20090136339 | METHODS AND APPARATUS TO FACILITATE SEALING IN ROTARY MACHINES - A method for assembling a rotary machine is provided. The method includes providing at least one seal assembly that includes at least one annular seal housing defined by a top wall, a front wall, and a rear wall, that are connected together such that a cavity is defined within the housing, coupling a plurality of flexible plates within the cavity such that the plates are axially-spaced from the front wall and the rear wall within the cavity, coupling at least one side plate to the at least one annular seal housing such that the at least one side plate is moveable with respect the front wall and the rear wall, and coupling the at least one sealing assembly within a rotary machine to facilitate sealing between a rotary component and a stator component. | 05-28-2009 |
| 20090206554 | STEAM TURBINE ENGINE AND METHOD OF ASSEMBLING SAME - A method is provided for assembling a turbine engine. The method includes providing a retro-fit seal ring assembly that includes a plurality of unitary, arcuate ring segments that are circumferentially-spaced about a center axis of the ring assembly. Each of the plurality of ring segments includes a body and at least one integrally formed tooth that extends radially inward therefrom. The methods also includes extending at least one fastener through the body of each of the plurality of ring segments, and removably coupling each of the plurality of ring segments to an outer surface of a stationary component within the turbine engine using the at least one fastener. | 08-20-2009 |
| 20090309311 | Methods and apparatus to facilitate sealing in rotary machines - 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. | 12-17-2009 |
| 20110200430 | STEAM TURBINE NOZZLE SEGMENT HAVING ARCUATE INTERFACE - Steam turbine nozzle segments with conical interfaces are disclosed. In one embodiment a steam turbine static nozzle blade includes: an airfoil; an inner sidewall integral with a first side of the airfoil; and an outer sidewall integral with a second side of the airfoil; the inner sidewall and the outer sidewall each including: a pressure side having an arcuate concave surface extending substantially an entire length of the sidewall; and a suction side having an arcuate convex surface extending substantially the entire length of the sidewall. | 08-18-2011 |
| 20110305566 | ADJUSTABLE SUPPORT APPARATUS FOR STEAM TURBINE NOZZLE ASSEMBLY - An adjustable support apparatus for a steam turbine nozzle assembly is disclosed. In one embodiment, a steam turbine apparatus includes: a diaphragm segment having a horizontal joint surface and an angled ledge below the horizontal joint surface, the angled ledge configured to receive a complementary angled portion of a wedge member. | 12-15-2011 |
