International Classification:

F23G 7/05
F23D 11/02

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.
