METHOD OF FORMING GASEOUS DRIPPING JET; PLANT FOR REALIZATION OF THIS METHOD AND NOZZLE FOR FORMING GASEOUS DRIPPING JET Russian patent published in 1998 - IPC

FIELD: generation of gaseous dripping jets of increased length; fire-fighting technique; irrigation systems in forming using long-range jets. SUBSTANCE: according to invention, gas pressure P and relative concentration of liquid g at nozzle inlet are selected from the following relationship: P•g ≤ 5,7•10⁸ Pa; P ≥ 5•10⁵ Pa, where g = G_l/G_g,; G_l is mass flow rate liquid and G_g is mass flow rate of gas. Water is used as liquid. Gas flow is created with at least one turbo-compressor plant. Length L of profiled passage of nozzle in plant is selected from relationship L ≥ 5d_th where d_th is diameter of nozzle throat section. Annular nozzle is used for performing this method. Gas supply system includes at least one turbo - compressor plant whose outlet device is connected with inlet of gas-dynamic nozzle. EFFECT: enhanced efficiency. 10 cl, 3 dwg
