Abstract: 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.

Abstract: An air blast fuel nozzle for a gas turbine engine includes a take apart head assembly having a large diameter air swirler for fuel flow from a pilot fuel distributor tube that is telescoped centrally within a take apart main fuel distributor and pilot nozzle element having means therein to form a thermal barrier air gap around the pilot fuel distributor tube and wherein the assembly further includes a main fuel distributor head having open ended axial fuel passages therethrough for supplying fuel to a main fuel distributing ring on the outboard end of the assembly immediately upstream of the air swirler.

Abstract: A method and apparatus particularly adapted for use in the continuous production of a foam material or the like.

Abstract: An airspray burner is supplied with fuel tangentially through a port and the upstream end of the burner is provided with a helical wall to prevent the fuel from passing back out of the fuel delivery port.

Abstract: A 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.

Abstract: A nozzle for atomizing fuel for use in gas turbines and the like especially suitable for atomizing fuels of high viscosity, said nozzle having a fuel swirl chamber with a trumpet or funnel-shaped orifice along which the fuel flows as a swirling conical sheet and being characterized in that said trumpet or funnel-shaped portion is perforated for admission of compressed air in swirling fashion to atomize the swirling conical sheet of fuel.

Abstract: An improved fuel injection apparatus is provided to uniformly disperse a low pressure fuel in a highly atomized manner for introduction into a combustion apparatus. The fuel injection apparatus of this invention employs a system of counter-rotating air swirl means disposed about a shroud member whereby the primary atomizing forces are the high shear stresses developed at the confluence of the counter-rotating air streams and the greater velocity and uniformity at which the fuel is dispersed within the shroud provides for a substantially increased atomization efficiency.

Abstract: A process for drawing in and compressing gases and mixing the same with liquid material, wherein the gases are first premixed with one or more liquid jets at a velocity of from 10 to 70 m/sec, the smallest cross-sectional area of the mixing nozzle being at a distance from the propulsive jet which is equal to from 1 to 10 times the smallest hydraulic diameter of the mixing nozzle, which smallest cross-sectional area of the mixing nozzle is equal to from 1.5 to 15 times the smallest cross-sectional area of the propulsive jet. The two-phase liquid mixture is passed through the mixing nozzle to the narrowest point of an impulse exchange tube disposed in the liquid medium, which impulse exchange tube is open at its inlet and outlet and is preferably provided with a diffuser. The smallest cross-sectional area of the impulse exchange tube is equal to from 1.
