Abstract: An atomizer includes an endcap having a nozzle; an annular sidewall extending outward from a surface of the endcap and situated radially outward from the nozzle; and a plurality of vanes extending radially inward from the sidewall and axially outward from the endcap, the vanes being set at a non-zero angle of incidence to the sidewall. The annular sidewall and endcap define an fluid chamber between an inlet and the nozzle, and flow from the inlet to the nozzle is at least partially directed through passageways between the vanes, and the flow is imparted with swirling motion from the vanes.

Abstract: A combustor including a first perforated layer including a first opening having a first diameter, wherein the first opening is configured to receive a flow of fluid including a fuel and air mixture; and impart a first rotational instability to the flow of fluid that is dependent on the first diameter; and a second perforated layer surrounding a combustion area, wherein the second perforated later includes a second opening having a second diameter, and wherein the second layer is located between the first layer and the combustion area.

Abstract: The disclosure describes a combustor suitable for burning emulsified crude oil and seawater, a flow-blurring atomizer positioned at first end configured for introducing atomized crude oil spray into an interior of the combustor. A shroud or combustion duct surrounds a portion of a burning plume of atomized crude oil. The shroud is connected to a base at the first end and is open at the opposite second end. Dilution holes extend through the base and/or the shroud, allow the aspiration and entrainment of air into the plume, and assist in the flame anchoring and propagation, and reduce the amount of soot produced by burning the emulsified oil. At least one ignition port directs an ignition flame or plasma toward the atomized crude oil spray. One or more abrupt expansions at the nozzle or at the shroud sidewalls form toroidal recirculation zones surrounding the atomized crude oil spray.
