  • Joint for sealing a gap between casing segments of an industrial gas turbine engine combustor
    Patent number: 10830447
    Abstract: A casing for a combustor includes an upstream segment, a downstream segment and a joint. The downstream segment is constructed and arranged to move telescopically with respect to the upstream segment and along a centerline. The joint includes a flange and bonding material, which attaches the flange to the upstream segment or the downstream segment. A melting point of the bonding material is less than a melting point of the flange and/or a melting point of the segments.
    Type: Grant

  • Gas turbine combustor liner cap assembly
    Patent number: 8572979
    Abstract: A combustor liner cap assembly is provided for use in a multiple fuel nozzle combustor of a gas turbine. The combustor liner cap assembly includes a tube plate having a plurality of fuel nozzle openings and a plurality of open ended premix tubes extending aft from the tube plate. Each premix tube has a forward end having a forward edge, the forward end being received in a corresponding one of the fuel nozzle openings. Each premix tube is secured to the tube plate aft of the forward edge of the forward end of the premix tube, for example, metallurgically bonded, such as by welding or brazing, to the tube plate or threaded into the tube plate.
