  • Patent number: 11020758
    Abstract: Flow blurring injection utilizes a two-phase concept to generate fine sprays immediately at the interior exit, rather than a typical jet which gradually disintegrates into ligaments and then finer droplets for a conventional injector. Therefore, clean combustion is achieved with the FB injection for fuels with distinct properties without fuel preheating or hardware modification. However, in addition to the droplets, the FB injection also produces ligaments for highly viscous liquids and relatively larger droplets at spray edge, resulting in difficulty in sustaining the flame and performs incomplete combustion and higher emissions close to the combustor all. The disclosed swirl burst injector and method utilizes the advantages of FB injection and swirl atomization to further improve atomization, and overcomes the limitations of FB injection, providing a sustainable way to use both conventional and alternative fuels with improved efficiency and minimized emissions.

  • Patent number: 9488086
    Abstract: An injector for delivering a working fluid into a working environment is disclosed. According to one embodiment of the present invention, the injector includes a pre-metering chamber and a swirl chamber. A high velocity partially atomized flow is produced in the pre-metering chamber through a first exit nozzle after impinging on an atomization element, and then a swirling flow is created in the swirl chamber with the atomization element. When the swirling flow is released through a second exit nozzle, atomization can be achieved at low injector pressure with centrifugal force and shearing of the working fluid. In another embodiment, the injector includes a swirl chamber and an atomization element with a bore, through which a control valve is positioned. The control valve forces a working fluid flow through the atomization element when the injector is energized to create a swirling flow. No flow-back is required for the injectors.
