International Classification:

F23R 3/42
B23P 15/00
US Classification:

60754, 2989001
Abstract:

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.

Assignee:

General Electric Company - Schenectady NY
International Classification:

B23C 5/02
US Classification:

4082035
Abstract:

An apparatus for removing retaining material proximate to a fastener on a surface is disclosed.

International Classification:

F02C 7/266
F23R 3/28
F23R 3/34
F23R 3/42
Abstract:

An igniter for a combustor of a turbomachine includes a fuel inlet in fluid communication with a mixing plenum. The mixing plenum is positioned upstream of a mixing channel. An air inlet is in fluid communication with the mixing plenum and an ignition source is in operative communication with the mixing channel. The igniter may include a mounting flange configured for coupling the igniter to the combustor. The ignition source may be positioned proximate to a downstream end of the mixing channel and upstream of the mounting flange. The mixing channel may define a venturi shape. The venturi shape includes a converging section between an upstream end of the mixing channel and a venturi throat.
