Abstract:
A power augmentation system for a gas turbine engine which 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 align with the transition piece passageways.
Abstract:
According to various embodiments, a system includes a turbine fuel nozzle. The turbine fuel nozzle includes a first fuel passage extending to a downstream mixing region, a first air passage extending from an exterior of the turbine fuel nozzle to the downstream mixing region, and a second fuel passage extending into the first air passage upstream of the downstream mixing region.
Abstract:
A turbomachine combustor assembly includes a combustor body, and a combustor liner arranged within the combustor body. The combustor liner defines a combustion chamber having a head end and a discharge end. A plurality of combustor nozzles are arranged in an annular array at the head end of the combustion chamber, and a fluid delivery nozzle is arranged substantially centrally within the annular array at the head end of the combustion chamber. The fluid delivery nozzle includes a first end portion that extends to a second end portion through a wall portion. The wall portion includes at least one combustion chamber outlet. The fluid delivery nozzle is configured to deliver a non-combustible fluid into the at least one of the plurality of combustor nozzles and the combustion chamber.
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:
A method for reducing the amount of carbon monoxide and oxygen emissions in a hydrocarbon combustor in a gas turbine engine by feeding hydrocarbon fuel and an oxidizer component into the head end of the combustor while also injecting substantially inert gas into the combustor with the fuel and oxidizer; forming a combustor exhaust stream that mixes with the recycle; cooling the combustor exhaust; detecting the amount of carbon monoxide and oxygen in the exhaust and adjusting the amount of fuel, oxidizer and inert gas feeds based on the detected amounts.
