摘要:
A combustor generally includes a liner that at least partially defines a combustion chamber within the combustor. The liner may generally include a hole that extends through the liner and that at least partially defines a mating surface. An insert having an outer surface extends at least partially through the hole. A projection that at least partially defines a mating surface at least partially circumferentially surrounds the insert outer surface. A joint between the projection mating surface and the hole mating surface provides a connection point between the projection mating surface and the liner hole mating surface.

A resilient annular seal structure is disposed radially between an aft end portion of a combustor liner and a forward end portion of a transition piece, the resilient annular seal structure configured to form a first annular cavity radially between the forward end portion of the transition piece and the aft end portion of said combustor. At least one transfer tube radially extends from the second flow sleeve through the second flow annulus to the transition piece, and is arranged to supply compressor discharge cooling air radially from an area outside the first and second substantially axially extending flow annuli directly to the resilient annular seal structure and to the aft end of the combustor liner.

A substantially wedge-shaped sector nozzle includes a nozzle body having inner and outer arcuate segments connected by diverging radial side plates and a nozzle plate at an aft end of the nozzle body formed with an array of fuel orifices. One of the diverging radial side plates supports a radially-oriented leaf seal assembly adapted to seal against a flat plate of an adjacent similarly-shaped sector nozzle.

An apparatus for removing retaining material proximate to a fastener on a surface is disclosed. The apparatus has a cavity dimensioned for receiving at least a portion of the fastener and has a non-abrasive face at its distal end. The apparatus also has a plurality of cutting inserts that are disposed proximate to the non-abrasive face and that each extend at least partially beyond the non-abrasive face while at least a portion of the non-abrasive face remains exposed to the surface. The cutting inserts are configured to rotate around the fastener to remove the retaining material.

An impingement shield assembly for a turbine includes a first impingement shield portion and a second impingement shield joined to the first impingement shield portion. The assembly also includes a first connection portion formed on the first impingement shield portion, a second connection portion formed on the first impingement shield portion and first and second wedge weld portions that mate with and hold the first and a second connection portions in a fixed relationship to one another.
