METHOD AND FACILITY FOR FIRE-FIGHTING Russian patent published in 1997 - IPC

FIELD: fire-fighting facilities. SUBSTANCE: method consists in accumulation of water in tank and of working gas in separate high-pressure cylinder. Both media are fed into spraying chamber where they are transformed into aerosol. Working gas is accumulated in addition under pressure in accumulating chamber and is fed over pipe-line, fast-action valve, system of nozzles into water under atmospheric pressure. Water is accumulated in spraying chamber, is divided and is thrown out through head to form fire-fighting mixture composed of finest not inter-coagulating particles. Areas of cross-section of pipe-line of facility communicating accumulating chamber with system of nozzles and of flow of fast-action valve exceed summary area of minimal diameters of nozzles. Accumulating chamber is connected to high-pressure cylinder of working gas through reducer, pipe-lines and fast-action valve. EFFECT: improved fire fighting capabilities of method and facility. 12 cl, 1 dwg
