AEROSOL GENERATOR FOR FIRE EXTINGUISHING Russian patent published in 1998 - IPC

FIELD: aerosol generators for volume aerosol fire extinguishing, functioning in capacity of generator of inhibitors of burning in the form of gas-aerosol products. SUBSTANCE: generator has explosive charge and cooling unit, both coaxially installed in generator body. Outlet holes are spaced on body cylinder surface. Located in perforated shell of cooling unit is layer of tablets or granules from cooling material. Body is heatproof. Charge is connected with starting device. Novelty consists in location of cooling unit with annular clearance relative to explosive charge. Volume of annular clearance fulfils additional function of combustion chamber and its geometry is optimized to ensure full final burning of explosive composition of charge in gas phase. EFFECT: higher efficiency of fire extinguishing due to increased rate of generation of fire extinguishing mixture with minimum content of harmful chemical substances. 1 dwg
