摘要： A method of forming an atomizing spray nozzle includes the steps of etching a swirl chamber and a spray orifice in a thin sheet of material. The swirl chamber is etched in a first side of the disk and the spray orifice is etched through a second side to the center of the swirl chamber. Feed slots are etched in the first side of the disk extending non-radially to the swirl chamber such that liquid can be conveyed to the swirl chamber so as to create and sustain the swirling motion. A inlet piece with inlet passage therein is connected with first side of the disk so as to convey liquid to the feed slots of the disk and to enclose the feed slots and swirl chamber. In addition to the method described an atomizing spray nozzle having the configuration described is much improved in its spray characteristics. The present invention also provides a method of forming a number of spray nozzles simultaneously in a single manufacturing process.

摘要： A combustor for an exhaust gas system includes a longitudinally compliant fuel conduit for allowing thermal expansion and contraction of other portions of the combustor relative to the fuel conduit while not misaligning the atomizer to which the fuel conduit is attached. The combustor includes an exhaust duct, a combustion chamber, and an air duct in addition to the atomizer and longitudinally complaint fuel conduit. The combustion chamber and air duct are disposed within the exhaust duct so that they are heated by the exhaust gases passing through the exhaust duct. The fuel conduit is disposed within the air duct so that air passing through the air duct keeps the fuel conduit relatively cool.

摘要： A gas turbine fuel injection nozzle is disclosed in which the secondary fuel is spread into a very thin film entirely within a region of low air momentum. The fuel is therefore not affected by turbulence, and this results in an evenly circumferentially distributed fuel film at the discharge orifice of the nozzle resulting in an even and extremely fine spray of fuel to enhance proper engine performance.

摘要： In a nozzle for atomizing fuel into a spray for combustion in gas turbine engines, wherein the atomization is effected by the use of high velocity and/or high density air, and wherein the supply of fuel to two separately metered points is such that at low flow rates the first fuel supply is spread into a thin sheet for atomization but at high flow rates the second fuel supply is spread into a thicker sheet which combines with the thin sheet produced from the first supply, thus resulting in a single spray of constant shape at all operating conditions.

摘要： A fuel nozzle wherein a swirl cone (36) is located between a housing (10) and a body (12). Body (12) cooperates with housing (10) to form an air chamber (32) and with cone (36) to form an inner annulus (40). Swirl vanes (34) are angularly mounted between cone (36) and body (12) such that air flowing from chamber (32) into annulus (40) forms a swirling flow pattern. Body (12) is provided with a fuel chamber (16) and radial passages (20) introduce fuel to the swirling air in inner annulus (40) to produce an atomized spray pattern.

摘要： A nozzle for atomizing fuel for combustion in a gas turbine engine. During normal operation of the engine, the nozzle uses a portion of the air supplied to the combustion chamber by the engine compressor to atomize fuel flowing through the nozzle. During start-up and low power operation of the engine when flow of engine air through the nozzle would otherwise be of insufficient velocity to cause good atomization of the fuel, additional air from a separate external source is introduced at high velocity into the nozzle in the manner of an ejector. The additional air imparts high velocity to the engine air within the nozzle so that the air from both sources acts on the fuel at the nozzle discharge orifice at high velocity to effect good atomization and spray pattern of the fuel. The nozzle is designed in such a manner as to cause no significant restriction of engine air flow through the nozzle under high power operation of the engine when the external air source is shut off.

摘要： An ultrasonic spraying device for atomizing a liquid and for breaking up into fine particles any solids contained in the liquid. The device comprises an acoustical horn in which ultrasonic vibration is induced by a generator and having a surface against which liquid may be impinged. The liquid is directed against the surface by one or more conduits that are external of the horn. Means is provided for adjusting the spacing and orientation of the conduits with respect to the impingement surface, for isolating the horn vibrationally from a support upon which the horn is mounted, and the impingement surface may be of several different shapes for controlling the direction in which the impinging liquid is deflected. The invention also relates to the method of utilizing an ultrasonic horn for atomizing liquids and for breaking up solids into small particles.
