VOLUMETRIC FIRE-EXTINGUISHING APPARATUS Russian patent published in 2003 - IPC

FIELD: fire-fighting equipment. SUBSTANCE: apparatus for generating gas-aerosol fire-suppressor produced upon burning of pyrotechnical compound and directed on object to be protected. Apparatus has cooling cylinder and casing arranged in axially aligned spaced relationship with respect to one another and fixed so as to define annular ejection gap between them. Casing is provided with heatproof layer of construction gypsum arranged around pyrotechnical charge. Receiver located above pyrotechnical charge is closed with cover equipped with igniter and distributing discharge openings made in the form of radial slots. Apparatus may be used in independent and automatic fire-suppressing systems designed for suppressing burning highly inflammable and combustible materials and electric equipment under voltage. EFFECT: simplified and compact construction, increased efficiency by increased discharge of fire-suppressing mixture actively cooled inside apparatus. 2 dwg
