A flameless combustor usable with multiple fuels comprises a combustion chamber and fuel lines in communication with the chamber.

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 rotating detonation engine (RDE) is disclosed which includes a housing, an injector assembly disposed within the housing, the injector assembly includes a fuel manifold, an oxidizer manifold, and a combustion chamber, fuel from the fuel manifold and an oxidizer from the oxidizer manifold are combined and combusted in the combustion chamber, each of the fuel and oxidizer manifolds communicates with the combustion chamber via a plurality of Tesla valves each via a corresponding port, 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 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.
