Side Wall Cooling For Nozzle Segments For A Gas Turbine

View page
US Patent:
6343911, Feb 5, 2002
Filed:
Apr 5, 2000
Appl. No.:
09/543460
Inventors:
Steven Sebastian Burdgick - Schenectady NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
F01D 904
US Classification:
415115, 415114, 415116, 415139
Abstract:
A nozzle vane segment includes outer and inner band portions with a vane extending therebetween and defining first and second cavities separated by an impingement plate for flowing cooling medium for impingement cooling of nozzle side walls. The side wall of each nozzle segment has an undercut region. The impingement plate has an inturned flange with a plurality of openings. Cooling inserts or receptacles having an open end are received in the openings and the base and side walls of the receptacles have apertures for receiving cooling medium from the first cavity and directing the cooling medium for impingement cooling of the side wall of the nozzle segment and a portion of the nozzle wall.

US Patent:
6375415, Apr 23, 2002
Filed:
Apr 25, 2000
Appl. No.:
09/557541
Inventors:
Steven Sebastian Burdgick - Schenectady NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
F01D 906
US Classification:
415115, 415114, 415116, 415189, 4152092
Abstract:
A nozzle stage segment includes inner and outer bands spaced radially one from the other with a nozzle vane therebetween. The outer band includes a wall defining a portion of the hot gas path flow through the turbine and an outer cover defining a chamber with the outer wall. The vane includes a vane extension integrally cast with the nozzle segment and extending into a vane extension on the cover. The cover mounts a forward hook for structurally mounting the nozzle segment to a fixed part of the turbine casing, thereby establishing a structural load path through the hook, the cover extension and the vane extension upon welding the extension to one another and the outer wall and cover to one another. Cavities in the vane open into the chamber to receive a cooling medium and which cavities and chamber form part of a closed circuit cooling path through the nozzle stage segment.

Apparatus And Methods For Impingement Cooling Of A Side Wall Of A Turbine Nozzle Segment

View page
US Patent:
6386825, May 14, 2002
Filed:
Apr 11, 2000
Appl. No.:
09/546770
Inventors:
Steven Sebastian Burdgick - Schenectady NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
F01D 906
US Classification:
415116, 415139
Abstract:
A gas turbine nozzle segment has outer and inner bands and a vane therebetween. Each band includes a nozzle wall, a side wall, a cover and an impingement plate between the cover and the nozzle wall defining two cavities on opposite sides of the impingement plate. Cooling steam is supplied to one cavity for flow through apertures of the impingement plate to cool the nozzle wall. The side wall of the band and inturned flange define with the nozzle wall an undercut region. The impingement plate has a turned flange welded to the inturned flange. A backing plate overlies the turned flange and aligned apertures are formed through the backing plate and turned flange to direct and focus cooling flow onto the side wall of the nozzle segment.

Closed Circuit Steam Cooled Turbine Shroud And Method For Steam Cooling Turbine Shroud

View page
US Patent:
6390769, May 21, 2002
Filed:
May 8, 2000
Appl. No.:
09/567296
Inventors:
Steven Sebastian Burdgick - Schenectady NY
Brendan Francis Sexton - Simpsonville SC
Iain Robertson Kellock - Simpsonville SC
Assignee:
General Electric Company - Schenectady NY
International Classification:
F04D 3100
US Classification:
415116, 415175
Abstract:
A turbine shroud cooling cavity is partitioned to define a plurality of cooling chambers for sequentially receiving cooling steam and impingement cooling of the radially inner wall of the shoud. An impingement baffle is provided in each cooling chamber for receiving the cooling media from a cooling media inlet in the case of the first chamber or from the immediately upstream chamber in the case of the second through fourth chambers and includes a plurality of impingement holes for effecting the impingement cooling of the shroud inner wall.

Airfoil Shape For A Turbine Nozzle

View page
US Patent:
6398489, Jun 4, 2002
Filed:
Feb 8, 2001
Appl. No.:
09/779226
Inventors:
Steven Sebastian Burdgick - Schenectady NY
Joseph Francis Patik - Cohoes NY
Gary Michael Itzel - Simpsonville SC
Assignee:
General Electric Company - Schenectady NY
International Classification:
F01D 904
US Classification:
415115, 415191, 4152082
Abstract:
A first-stage nozzle vane includes an airfoil having a profile according to Table I. The annulus profile of the hot gas path is defined in conjunction with the airfoil profile and the profile of the inner and outer walls by the Cartesian coordinate values given in Tables I and II, respectively. The airfoil is a three-dimensional bowed design, both in the airfoil body and in the trailing edge. The airfoil is steam and air-cooled by flowing cooling mediums through cavities extending in the vane between inner and outer walls.

Leaf Seal For Gas Turbine Stator Shrouds And A Nozzle Band

View page
US Patent:
6402466, Jun 11, 2002
Filed:
May 16, 2000
Appl. No.:
09/571814
Inventors:
Steven Sebastian Burdgick - Schenectady NY
Brendan Francis Sexton - Simpsonville SC
Assignee:
General Electric Company - Schenectady NY
International Classification:
F10D 1108
US Classification:
4151733, 415135, 415139, 4151731, 4151742, 4152092, 277630, 277631, 277637, 277644
Abstract:
A leaf seal assembly is secured to the trailing edge of a shroud segment for sealing between the shroud segment and the leading edge side wall of a nozzle outer band. The leaf seal includes a circumferentially elongated seal plate biased by a pair of spring clips disposed in a groove along the trailing edge of the shroud segment to maintain the seal plate in engagement with the flange on the leading edge side wall of the nozzle outer band. The leaf seal plate and spring clips receive pins tack-welded to the shroud segment to secure the leaf seal assembly in place.

Support Pedestals For Interconnecting A Cover And Nozzle Band Wall In A Gas Turbine Nozzle Segment

View page
US Patent:
6413040, Jul 2, 2002
Filed:
Jun 13, 2000
Appl. No.:
09/593276
Inventors:
Yufeng Phillip Yu - Simpsonville SC
Gary Michael Itzel - Simpsonville SC
Waylon Willard Webbon - Greenville SC
Radhakrishna Bagepalli - Schenectady NY
Steven Sebastian Burdgick - Schenectady NY
Iain Robertson Kellock - Simpsonville SC
Assignee:
General Electric Company - Schenectady NY
International Classification:
F01D 514
US Classification:
415115, 415116, 415191, 4152082
Abstract:
A gas turbine nozzle segment has outer and inner band portions. Each band portion includes a nozzle wall, a cover and an impingement plate between the cover and nozzle wall defining two cavities on opposite sides of the impingement plate. Cooling steam is supplied to one cavity for flow through the apertures of the impingement plate to cool the nozzle wall. Structural pedestals interconnect the cover and nozzle wall and pass through holes in the impingement plate to reduce localized stress otherwise resulting from a difference in pressure within the chamber of the nozzle segment and the hot gas path and the fixed turbine casing surrounding the nozzle stage. The pedestals may be cast or welded to the cover and nozzle wall.

Recessed Impingement Insert Metering Plate For Gas Turbine Nozzles

View page
US Patent:
6416275, Jul 9, 2002
Filed:
May 30, 2001
Appl. No.:
09/681738
Inventors:
Gary Michael Itzel - Greenville SC, 29680
Steven Sebastian Burdgick - Schenectady NY, 12303
International Classification:
F01D 904
US Classification:
415116, 416115
Abstract:
An impingement insert sleeve is provided that is adapted to be disposed in a coolant cavity defined through a stator vane. The insert has a generally open inlet end and first and second diametrically opposed, perforated side walls. A metering plate having at least one opening defined therethrough for coolant flow is mounted to the side walls to generally transverse a longitudinal axis of the insert, and is disposed downstream from said inlet end. The metering plate improves flow distribution while reducing ballooning stresses within the insert and allowing for a more flexible insert attachment.
