The present application provides a combustor. The combustor may include a fuel supply line, a fuel nozzle, and a number of flow-device pathways connecting the fuel supply line and the fuel nozzle. The flow-device pathways may include a counter-swirl configuration.

Material handling systems for fluids are disclosed herein. The fluid may be a liquid, solution, slurry, or emulsion. The systems receive as inputs the fluid, steam, and water. These feed into a surge tank where additives can be introduced. The steam and water are used to control some physical properties and enable the distribution of the fluid as desired. In particular embodiments, the system is useful for handling materials to be sent to a dual-phase fuel feeder for combustion in a fluidized-bed boiler, the energy being used to generate electricity or in various production processes.

A method for assembling a fuel distribution system for a turbomachine fuel injector includes inserting a liquid fuel distributor into an interior cavity of a shroud to create a liquid fuel distribution circuit between the liquid fuel distributor and the shroud and inserting a gas fuel distributor into the interior cavity of the shroud and into an interior cavity of the liquid fuel distributor to create a gas fuel distribution circuit between the gas fuel distributor and the liquid fuel distributor. The method includes inserting a fuel transfer tube into an outer diameter of the shroud. The method includes brazing or shrink fitting at least one of the fuel transfer tube, the gas fuel distributor, or the liquid fuel distributor to the shroud.

A fuel supply manifold for a gas turbine engine includes a first manifold segment includes a first multiple of double-barrel fittings in communication with a primary fuel circuit and a secondary fuel circuit.

A combustion method is disclosed, which includes the steps of mixing fuel and an oxidizer into a mixture, wherein fuel originates from a fuel manifold and the oxidizer originates from an oxidizer manifold, and combusting the mixture in a combustion chamber, the fuel manifold, the oxidizer manifold, and the combustion chamber forming parts of an injector assembly wherein each of the fuel and oxidizer manifolds communicates with the combustion chamber via a plurality of dedicated radially disposed Tesla valves around the combustion chamber each via a corresponding port with only one Tesla valve between the fuel manifold and the corresponding port on the combustion chamber and with only one Tesla valve between the oxidizer manifold and the corresponding port on the combustion chamber, wherein the plurality of Tesla valves substantially eliminate reverse flow of exhaust gases from the combustion chamber back to the fuel manifold or the oxidizer manifold.

A fuel supply system includes a metering and splitting arrangement receiving a fuel flow and controllably meters and splits the received fuel flow into metered pilot and mains flows for injecting at injector pilot and mains fuel discharge orifices to perform combustor staging control. The system includes an ecology valve having a piston chamber and a piston slidably movable in the chamber between de-prime and re-prime positions, the chamber forming a fuel sink to one side of the piston which increases in volume when the piston moves to its de-prime position and reduces in volume when the piston moves to its re-prime position. The system includes an actuator for actuating the piston. The valve is fluidly connected to a mains fuel distribution for operating the piston to its de-prime position to remove the mains fuel from the injectors through the mains fuel distribution pipework and into the fuel sink.
