    摘要: In a gas turbine having a chordal hinge seal between an inner rail of each nozzle segment and an annular axially facing sealing surface of a nozzle support ring, a supplemental seal is disposed between the support ring and inner rail of the nozzle segment on a high pressure side of the chordal hinge seal. The supplemental seal includes a sheet metal seal supported by a bracket secured to the back side and radial inner surfaces of the inner rail. The sheet metal seal has a flexible margin which is preloaded and bears against the annular sealing surface of the nozzle support ring. The bracket is bolted or welded to the inner rail with the sheet metal seal therebetween inhibiting or precluding leakage past the back side of the supplemental seal.

    摘要: A seal assembly includes a cloth seal for sealing a cavity between a first mating body and a second mating body, the seal dividing the cavity into a high pressure region and a low pressure region. The cloth seal has a shim assemblage and a cloth assemblage. A first peripheral portion of the cloth seal may include a portion of the cloth assemblage and/or the shim assemblage which contacts the high pressure region and a second peripheral portion including a portion of the cloth assemblage adapted to contact the low pressure region. Knowing the flow conditions and pressure differential through the seal, the density of the cloth seal may be calibrated to control leakage and the shim and cloth assemblages may be designed to minimize contact loads on a mating body.

    摘要: A fuel nozzle centering assembly and method employ bodies of a substantially wearable and sacrificial material mounted to an outer periphery of a tip of a burner fuel nozzle for a gas turbine combustor. The tip of the fuel nozzle extends through an opening of an annular collar attached to a liner of a main combustion chamber of the gas turbine combustor and an outer periphery of the tip is disposed radially inwardly from the annular collar such that the bodies of sacrificial material are disposed between the outer periphery of the fuel nozzle tip and the annular collar of the liner and space the fuel nozzle tip from the liner collar. The bodies of material prevent the fuel nozzle tip from contacting the liner collar during assembling of the fuel nozzle into the liner. The bodies wear away substantially upon initial operation of the combustor such that the bodies will reduce contact with the liner collar during further operation of the combustor and the fuel nozzle tip will remain spaced from and out of contact with the liner collar during operation of the combustor.

    摘要: In a combustor having an axis, a flow sleeve and a liner, a plurality of circumferentially spaced supports interconnect the upstream ends of the liner and flow sleeve to limit wear on the supports and accommodate relative thermal expansion of the liner and flow sleeve. Each support includes a flow sleeve stop having an angled surface, a groove and a female threaded aperture and a liner stop having a complementary angled surface, a rib and an enlarged opening. By inserting the liner axially through the open upstream end of the flow sleeve, the rib of the liner stop engages the slot of the flow sleeve stop. By passing a bolt having a spring through the enlarged opening of the liner stop and threading the bolt to the flow sleeve stop, the liner is biased for axial downstream movement to maintain the complementary inclined surfaces of the stops in contact with one another, thereby limiting wear and accommodating relative thermal expansion of the flow sleeve and liner.
