System and method to locate and repair insert holes on a gas turbine component

A method for repairing a bundled tube fuel injector includes removing a portion of a pre-mix tube, aligning a tube tip with the remaining portion pre-mix tube and fixedly connecting the tube tip to the pre-mix tube. The method may further include removing an aft plate and an outer shroud from the bundled tube fuel injector so as to expose the pre-mix tube.

A system for adaptively machining a shroud of a blade used in a turbomachine is provided. The system may include a computer system including a module(s) configured to: extract geometric location data from a 3D model of the shroud after use in the turbomachine, the 3D model created by digitizing using a digitizing device. The geometric location data includes geometric location data of a hard face plane of the shroud exposed to wear during turbomachine operation and of a non-worn surface adjacent to the hard face plane substantially unexposed to wear during turbomachine operation. Comparing the geometric location data of the non-worn surface from the three-dimensional model to a manufacturing model of the blade determines a change in position of the non-worn surface from use of the blade in the turbomachine. The change in position is used to modify a machining instruction used by a machining device to repair the hard face plane.

A bundled tube fuel injector includes an outer band that circumferentially surrounds a fuel plenum defined within the bundled tube fuel injector. The outer band includes a forward end portion that is axially separated from an aft end portion. A plurality of pre-mix tubes extends through the fuel plenum substantially parallel to one another. A first segment of the plurality of pre-mix tubes is circumferentially surrounded by the outer band. An outer shroud extends circumferentially around a second segment of the pre-mix tubes. The outer shroud includes a forward portion and an aft portion. The aft end portion of the outer band is coupled to the forward portion of the outer shroud via a plurality of fasteners for enhanced assembly and reparability.

Various embodiments include apparatuses adapted to be used as a replacement oil cartridge tip. In some embodiments apparatuses include a replacement swirler ring for an oil cartridge tip, the replacement swirler ring having an annular main body including an inner diameter surface sized to be joined to an outer diameter surface of the oil cartridge tip by a metal joining process including one of brazing, welding temperature or mechanical interference and an outer diameter surface including channels evenly spaced about a primary axis of the annular main body, wherein the annular ring includes a material that is at least as wear-resistant as a material of the oil cartridge tip.

Replacement oil cartridge tip and method

Blockages of turbomachine cooling circuit cooling holes resulting from coating processes can be removed by introducing a cleaning agent into the cooling circuit. The cooling circuit can be connected to a cleaning agent supply under pressure, adding force on the blockage to chemical action by the cleaning agent. The cleaning agent is chemically reactive with the coating material and substantially chemically non-reactive with the underlying material of the cooling circuit and other parts of the turbomachine. A neutralization agent can also be introduced to reduce toxicity and/or action of the cleaning agent. A turbomachine cooling hole cleaning method includes introducing a cleaning agent into a cooling circuit of a turbomachine part, pressurizing the cleaning agent in the cooling circuit until a first defined condition is met, and introducing a neutralization agent to the turbomachine part while the cleaning agent is applied to the cooling circuit.

A bundled tube fuel injector includes a fuel distribution module, a tube bundle having a plurality of pre-mix tubes that extend in parallel downstream from the fuel distribution module and a support plate disposed substantially adjacent to the fuel distribution manifold. The plurality of pre-mix tubes extends through the support plate. A retention sleeve is coupled to the support plate at a first end. A second end of the retention sleeve includes a plurality of radially extending retention features that are circumferentially arranged around the second end. The bundled tube fuel injector also includes an aft plate having a retention collar. The retention collar is configured to engage with the retention features. The retention sleeve and the retention collar partially define a cartridge passage that extends through the bundled tube fuel injector.

A bundled tube fuel injector includes a fuel plenum that is defined within the bundled tube fuel injector and a plurality of pre-mix tubes that extend downstream from the fuel plenum substantially parallel to one another. Each pre-mix tube includes an end portion and a radially extending end surface. The bundled tube fuel injector further includes a tube tip that is fixedly connected to the end portion of a corresponding pre-mix tube.

A method for disassembling a bundled tube fuel injector includes decoupling an aft plate from a fuel distribution module of the bundled tube fuel injector, where the aft plate is disposed at a downstream end of the bundled tube fuel injector. The method also includes removing the aft plate from the bundled tube fuel injector to expose a portion of a plurality of pre-mix tubes so as to allow for inspection repair and/or replacement of one or more of the plurality of pre-mix tubes.

According to one aspect of the invention, a method for servicing a combustor cap assembly of a turbine includes determining a defect is present in a center ring of the cap assembly, the center ring being disposed within a plurality of vanes, removing the center ring from the cap assembly. The method also includes placing a replacement center ring in the cap assembly, wherein dimensions of the replacement center ring are substantially the same as the center ring that has been removed and brazing the replacement center ring to the plurality of vanes.

Method for servicing a combustor cap assembly for a turbine

A fixture and method for adjusting a workpiece are disclosed. The fixture includes a holding device engageable to a workpiece to secure the workpiece, and an adjustment device engageable to a projecting member of the workpiece and movable along a first axis and a second axis. Movement of the adjustment device along the first axis when engaged to the projecting member adjusts the projecting member along the first axis, and movement of the adjustment device along the second axis when engaged to the projecting member adjusts the projecting member along the second axis.

Fixture and method for adjusting workpiece

A combustor generally includes a plate that extends radially and circumferentially within at least a portion of the combustor. The combustor may also include a shroud that at least partially surrounds the plate and a plurality of tubes that extend through the plate. One or more flexible couplings may at least partially surround at least some of the plurality of tubes and the one or more flexible couplings may be connected to the plate.
