摘要： 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. The fine atomization of the present invention can be also used in various applications where fine sprays are needed.

摘要： A liquid atomization process comprises forming a two-phase fluid mixture of a liquid and a gas, under pressure, dividing the fluid into two separate streams which are passed into and through an impingement mixing zone in which they are impingement mixed to form a single stream of two-phase fluid. The mixed, single stream is then passed into and through a shear mixing zone and then into a lower pressure expansion zone, in which atomization occurs to form a spray of atomized drops of the liquid. The impingement and shear mixing zones comprise respective upstream and downstream portions of a single fluid passageway in a nozzle. This is useful for atomizing the hot feed oil in an FCC process.
摘要翻译：液体雾化方法包括在压力下形成液体和气体的两相流体混合物，将流体分成两个分离的流，所述两个流分别流入并通过冲击混合区，在冲击混合区中它们被冲击混合以形成单流的两相流体。然后将混合的单一流进入并通过剪切混合区，然后进入低压膨胀区，其中发生雾化以形成液体的雾化液滴的喷雾。冲击和剪切混合区域包括在喷嘴中的单一流体通道的各自的上游和下游部分。这对于在FCC工艺中雾化热进料油是有用的。

摘要： The device for forming an aerosol has a device for adjusting the amount of particle former transported by the spray jet per time unit and/or a device for adjusting the amount of compressed gas passing per time unit through the wall. Such a device can be used for fluid treatment of sensitive, easily deformable objects, especially for their cooling, or other applications requiring certain metering of the particle formation, for example, in a burner. By providing a permeable wall having pores, it is possible to produce fluid particles with minimal kinetic energy by the effect of the compressed gas flowing through the permeable wall so that at the exit side of the wall a fluid particle stream with particles having extremely low energy per particle can be produced.

摘要： Method and apparatus to prevaporize and premix liquid and/or gaseous fuels with air in two stages at two different temperatures prior to combustion. The invention is directed to the entry of a finely atomized liquid fuel, such as No. 2 diesel, into an inlet end of an annular chamber. Air is mixed with finely atomized liquid fuel, preferably generated by a small flow number liquid fuel nozzle, in a first chamber of the annular chamber at a first (relatively high) temperature for a relatively long residence time. The air and liquid fuel is moved into a second chamber of the annular chamber where a secondary hotter air is injected into the annular chamber by a plurality of staggered high velocity jets to prevaporize and premix the combined fuel and air mixture at a second higher temperature, but for a shorter time. The intense prevaporization and premixing make the mixture suitable for entry into a combustor, but without the need to add water or steam to keep pollutant emissions low. Alternatively, the invention may be used with a gaseous fuel and air, or the combination of liquid fuel and gaseous fuel and air. A sharp-edged film atomizer may be added to provide secondary atomization of the liquid fuel.

摘要： A fuel nozzle assembly having a fuel nozzle tip at one end of a fuel delivery tube and a supporting flange at the other end. An air delivery tube, also secured to the support flange, encloses the fuel delivery tube to define an annular air passage therebetween. An integral fuel nozzle/end cap engages the fuel and air tubes and provides passages for fuel flowing from the fuel delivery tube and air flowing from the air delivery tube. Biasing means exerts an axial force on the air delivery tube to tighten the engagement of the tubes into an air-tight fit.
