摘要： A combustor includes an end cap having an upstream surface axially separated from a downstream surface. A cap shield circumferentially surrounds the upstream and downstream surfaces, tubes extend from the upstream surface through the downstream, and a plenum is inside the end cap. A first baffle extends radially across the plenum toward the cap shield, and a plate extends radially inside the plenum between the first baffle and the upstream surface. A method for supplying fuel to a combustor includes flowing a working fluid through tubes, flowing a fuel into a plenum between upstream and downstream surfaces, radially distributing the fuel along a first baffle, and axially flowing the fuel across a plate that extends radially inside the plenum.

摘要： A combustor includes an end cap having upstream and downstream surfaces and a cap shield surrounding the upstream and downstream surfaces. First and second sets of premixer tubes extend from the upstream surface through the downstream surface. A first fuel conduit supplies fuel to the first set of premixer tubes. A casing circumferentially surrounds the cap shield to define an annular passage, and a second fuel conduit supplies fuel through the annular passage to the second set of premixer tubes. A method for supplying fuel to a combustor includes flowing a working fluid through first and second sets of premixer tubes, flowing a first fuel into the first set of premixer tubes, and flowing a second fuel through an annular passage surrounding the end cap and into the second set of premixer tubes.

摘要： A combustor includes an end cap having an upstream surface axially separated from a downstream surface. A casing circumferentially surrounds at least a portion of the end cap to define an annular passage. A first tube bundle extends from the upstream surface through the downstream surface to provide fluid communication through the end cap. A first fuel conduit is in fluid communication with the first tube bundle to supply fuel through the annular passage to the first tube bundle, and a liquid fuel supply is in fluid communication with the first tube bundle through the first fuel conduit. A method for supplying fuel to a combustor includes flowing a working fluid through a first tube bundle and flowing a liquid fuel through an annular passage surrounding the end cap and into the first tube bundle.

摘要： A combustor includes an end cover, an end cap downstream from the end cover, and tubes that extend through the end cap. An outer support tube extends downstream from the end cover and connects to an upstream surface of the end cap. An inner support tube extends downstream from the end cover and connects to a downstream surface of the end cap. A first plenum surrounds the inner support tube between the end cover and the upstream surface and extends radially between the upstream and downstream surfaces. A second plenum surrounds the first plenum between the end cover and the upstream surface and extends radially between the upstream and downstream surfaces.

摘要： A transition duct for a combustor of a gas turbine generally includes a transition duct having a frame at an aft end of the transition duct. The frame generally includes a downstream end, a radially outer portion, a radially inner portion opposed to the radially outer portion, a first side portion between the radially outer and inner portions, and a second side portion opposed to the first side portion. A slot in the first side portion of the frame may have a downstream surface adjacent to the downstream end of the frame. A heat shield having an inner surface, an outer surface and a plurality of spacers may extend generally outward from the heat shield inner surface such that the inner surface is adjacent to the slot downstream surface and the frame downstream end.
