Abstract:
The present application provides a combustor (25) for combusting a flow of air and a flow of fuel. The combuster may include a number of fuel nozzles (110), an air path with the flow of air therein leading to the fuel nozzles, and a manifold (230) positioned in the air path upstream of the fuel nozzles. The manifold may include a number of resonator tubes (250).
Abstract:
A turbomachine combustor assembly includes a combustor body having a combustor outlet, and a combustion liner arranged within the combustor body. The combustion liner defines a combustion chamber. An injection nozzle is arranged within the combustor body upstream from the combustion chamber. The injection nozzle is configured and disposed to deliver a first fluid toward the combustion chamber. A fluid module is mounted to the combustor body downstream from the combustion chamber. The fluid module includes a fluid module body that defines a fluid zone, a first injector member mounted to the fluid module body and configured to deliver a second fluid into the fluid zone at a first orientation, and a second injector member mounted to the fluid module body and configured to deliver a third fluid into the fluid zone at a second orientation that is distinct from the first orientation.
Abstract:
The present application provides a power augmentation system with dynamics damping for a gas turbine engine. The power augmentation system may include a transition piece of a combustor and a steam manifold positioned about the transition piece. The transition piece may include a number of transition piece passageways therethrough and the steam manifold may include a number of manifold passageways therethrough. The manifold passageways may align with the transition piece passageways.
Abstract:
A turbomachine combustor assembly includes a combustor body (20), and a combustor liner (24) arranged within the combustor body (20). The combustor liner (24) defines a combustion chamber (30) having a head end (32) and a discharge end (37). A plurality of combustor nozzles (44-49) are arranged in an annular array at the head end (32) of the combustion chamber (30), and a fluid delivery nozzle (90) is arranged substantially centrally within the annular array at the head end (32) of the combustion chamber (30). The fluid delivery nozzle (90) includes a first end portion (98) that extends to a second end portion (99) through a wall portion (100). The wall portion (100) includes at least one combustion chamber outlet (113). The fluid delivery nozzle (90) is configured to deliver a non-combustible fluid into the at least one of the plurality of combustor nozzles (44-49) and the combustion chamber (30).
Abstract:
The present application provides a combustor cap (110) for use with a number fuel nozzles (130,140). The combustor cap may include a cold side plate (160) hot side plate (150), and a cap cavity (170) extending between the cold side plate and the hot side plate with the number of fuel nozzles extending therethrough. A resonator tube (180) may extend from the cold side plate into the cap cavity.
