Jr.Attorney, Agent or FirmInternational ClassF23D 11/10 (20060101)AbstractA fuel injection nozzle for gas turbines in which atomization of the liquid fuel is accomplished by high-velocity air entering the combustion chamber, characterized by minimizing the surface area of metal in contact with the fuel during the atomization process and further characterized by designing the air passages such that a swirling motion is imparted to the air followed by an acceleration of the air stream to eliminate variations in air velocity and to maximize air velocity at the point of impact with the fuel.Field of SearchIncluding whirler device to induce fluid rotationThree or more fluids Plural serially arranged whirlers for same or for mixed fluids Adjustable or selective whirl inducing means Whirling of fluid prior to or at point of addition of second fluid Discrete whirler means for each fluid Fluid in outer of concentrically arranged paths is whirled Mixing at or downstream of terminus Concentric flow paths At or beyond outlet Two of three disparate fluids premixed Induction of ambient air Combining of three or more separate fluid streams Concurrent or concentric flow means Flow means of one fluid surrounds the other at outlet Ambient air aspirated through inner flow path Serially arranged mixing zones (i.e., of same or mixed fluids) Additions of fluid in zones spaced along flow path At least three diverse fluids | |
