SYSTEM FOR FIRE EXTINGUISHING Russian patent published in 2010 - IPC A62C31/02 B05B1/02 

FIELD: health, fire prevention means.

SUBSTANCE: system for fire extinguishing is intended for extinguishing of forests in limited space. In order to achieve technical result, system comprises reservoir for fire-extinguishing medium, fire detectors, spraying heads and pipelines for supply of fire-extinguishing medium into spraying heads, made of two parts. One part of head is arranged in the form of truncated cone with holes for air supply and nozzle, and the other one - in the form of cone, inside of which there are metal cylinders installed one into another, which are fixed to each other by means of metal partitions, and plug with reverse cone, which is installed in central cylinder. Space between cone and external metal cylinder is plugged to produce hole in upper part of head.

EFFECT: increased efficiency of hot spots extinguishing in closed areas due to prevention of air flows circulation processes in zone of combustion; invention makes it possible to both efficiently cool zone of combustion and ascending flow of combustion products, to prevent circulation of air in premises, thus increasing efficiency of fire extinguishing with high temperature in hot sport, and also to clean air supplied into spraying head, from combustion products.
