Abstract
Fuel distribution manifolds and combustors are provided. A fuel distribution manifold includes a main body and a fuel circuit that is defined within the main body. The fuel circuit includes an inlet section extending generally axially from an inlet to a first branch section and a second branch section. The first branch section and the second branch section diverge circumferentially away from each other as they extend axially from the inlet section to a respective first outlet and a respective second outlet.
Claims18
A fuel distribution manifold coupled to a combustor casing of a combustor, the fuel distribution manifold comprising:
- a main body comprising a radially outer face, a radially inner face, a first side extending from the radially outer face towards an axial centerline of the combustor to the radially inner face, and a second side spaced from the first side and extending from the radially outer face towards the axial centerline of the combustor to the radially inner face;
- a fuel circuit defined within the main body, the fuel circuit comprising:
- an inlet section extending generally axially from a main inlet;
- a first branch section fluidly coupled to the inlet section, the first branch section including a first oblique portion and a first circumferential portion, the first oblique portion extending from a first inlet to the first circumferential portion, the first circumferential portion extending from the first oblique portion to a first outlet;
- and
- a second branch section fluidly coupled to the inlet section, the second branch section including a second oblique portion and a second circumferential portion, the second oblique portion extending from a second inlet to the second circumferential portion, the second circumferential portion extending from the second oblique portion to a second outlet;
- wherein the first branch section and the second branch section diverge circumferentially away from each other as the first branch section and the second branch section extend axially from the inlet section to the first outlet and the second outlet, respectively.
A combustor, comprising:
- a combustor casing and an end cover coupled to the combustor casing;
- a primary fuel nozzle that extends axially downstream from the end cover within the combustor casing;
- a primary combustion zone defined downstream from the primary fuel nozzle;
- a plurality of fuel injectors downstream from the primary combustion zone;
- a fuel distribution manifold coupled to the combustor casing of the combustor and fluidly coupled to the plurality of fuel injectors, the fuel distribution manifold comprising:
- a main body comprising a radially outer face, a radially inner face, a first side extending from the radially outer face towards an axial centerline of the combustor to the radially inner face, and a second side spaced from the first side and extending from the radially outer face towards the axial centerline of the combustor to the radially inner face;
- a fuel circuit defined within the main body, the fuel circuit comprising:
- an inlet section extending generally axially from a main inlet;
- a first branch section fluidly coupled to the inlet section, the first branch section including a first oblique portion and a first circumferential portion, the first oblique portion extending from a first inlet to the first circumferential portion, the first circumferential portion extending from the first oblique portion to a first outlet;
- and
- a second branch section fluidly coupled to the inlet section, the second branch section including a second oblique portion and a second circumferential portion, the second oblique portion extending from a second inlet to the second circumferential portion, the second circumferential portion extending from the second oblique portion to a second outlet;
- wherein the first branch section and the second branch section diverge circumferentially away from each other as the first branch section and the second branch section extend axially from the inlet section to the first outlet and the second outlet, respectively.
