A system includes a combustor for a gas turbine defining a main axis extending in an upstream-downstream direction, the combustor including a combustor dome bounding an upstream portion of the combustor, wherein a plurality of injector openings are defined through the combustor dome. An injector defines a spray axis aligned with one of the plurality of injector openings for issuing a spray into the combustor along the spray axis. An actuator is operatively connected to the injector for movement of the injector relative combustor dome to adjust a relative position of the spray axis relative to the main axis to alter the position and/or direction of the spray injector during operation of the gas turbine engine.

A fluid nozzle includes a first fluid circuit, a second fluid circuit spaced apart from the first fluid circuit and a fuel circuit. The fuel circuit is defined between the first and second fluid circuits and between a first fuel circuit wall and a second fuel circuit wall. A ring-shaped permeable barrier is positioned between the first and second fuel circuit walls configured and adapted to provide a controlled resistance to fuel flow. A fuel distributor includes a first fuel circuit wall and a second fuel circuit wall spaced apart from the first fuel circuit wall. A fuel circuit is defined between the first and second fuel circuit walls. A ring-shaped permeable barrier is positioned between first and second fuel circuit walls. A combustion assembly includes a combustor housing, a combustor dome positioned at an upstream end of the combustor housing, and a fluid nozzle positioned adjacent the combustor dome.

Fluid distributors for fluid nozzles

An atomizer includes an atomizer body with a plurality of air passages defined therethrough from an upstream end of the atomizer body to a downstream end thereof. The air passages together define an air circuit through the atomizer body. A fuel circuit is defined in the atomizer body extending from a fuel inlet to a respective fuel outlet opening into each air passage. The air passages can be arranged circumferentially about a central axis defined by the atomizer body. The fuel circuit can include a manifold extending circumferentially about the atomizer body in fluid communication with a fuel opening in each respective air passage.

Atomizers

A fuel injector for an exhaust heater includes a cover and an air blast nozzle. The cover has a nozzle seat, a fuel inlet, and an air inlet, the nozzle seat arranged along a flow axis. The air blast nozzle is seated in the nozzle seat and has a unibody. The air blast nozzle unibody is in fluid communication with the fuel inlet and the air inlet arranged along the flow axis to port fuel and air into a combustion volume, e.g., to heat a stream of exhaust gas flowing between an engine and a catalytic reactor by combustion with fuel introduced through the fuel inlet and air introduced through the air inlet.

Fuel injectors for exhaust heaters

A spray nozzle comprising a housing including a primary passage defining a primary axis, a series of secondary passages configured to provide swirl to a fluid passing therethrough circumferentially positioned around the housing, a series of standoffs circumferentially spread around an outer surface of the housing and located downstream along the primary axis of the series of swirling passages, wherein each of the swirling passages corresponds to a respective standoff of the series of standoffs, in order to control the swirl of the fluid.

Spray nozzle

A nozzle includes an outer gas flow path, an inner gas flow path radially inward from the outer gas flow path, a liquid flow path defined radially between the inner gas flow path and the outer air flow path, and a core conduit defined radially inward from the inner gas flow path. An injector assembly includes an outer housing, a nozzle within the outer housing, and an outer housing gas flow path defined radially outward from the nozzle between an inner surface of the outer housing and an outer surface of the nozzle. The nozzle includes an outer gas flow path, an inner gas flow path radially inward from the outer gas flow path, a liquid flow path defined radially between the inner gas flow path and the outer gas flow path and a core conduit defined radially inward from the inner gas flow path.

Mixing nozzles
