ACOUSTIC SPRAY NOZZLE (DESIGN VERSIONS) Russian patent published in 2000 - IPC

FIELD: spraying fuel of all kinds. SUBSTANCE: spray nozzle used for atomizing and burning liquid, gaseous, gas-liquid, multicomponent, and multiphase fuels in various processes including engines and reactors of flying vehicles, as well as for process carbon producing reactors has body, swirl chamber with tangential inlet channels and central outlet nozzle, and toroidal swirl chamber. Spherical swirl chamber is provided with cylindrical resonant box designed for varying its volume. Spray nozzle body has additional swirl chambers which are mounted normal to device axis. In addition, spray nozzle has cowling incorporating toroidal swirl chamber and spherical cavities intercommunicating through matching channels. Central outlet nozzle may be made in the form of converging-diverging nozzle. High-power acoustic energy is generated to produce impact on fuel atomizing and combustion process. In addition, provision is made for controlling output characteristics of spray nozzle. EFFECT: improved fineness of atomized fuel and its combustion process. 10 cl, 6 dwg
