FIRE SUPPRESSION METHOD SYSTEM Russian patent published in 2006 - IPC A62C3/00 A62C35/00 

FIELD: fire fighting, particularly to extinguish fire in large volatile flammable liquid storage facilities under low ambient temperatures in northern zones.

SUBSTANCE: method involves delivering fire-extinguishing powder via pipeline to fire site so that fire-extinguishing powder is fluidized and aerated along the full pipeline length. Fire-extinguishing system comprises fire-extinguishing powder supply pipeline installed in potential fire initiation zone, accumulation vessels for fire-extinguishing powder, compressed gas source and alarm means. The supply pipeline has gas-permeable longitudinal partition, which divides the pipeline into low-pressure and high-pressure cavities. The pipeline is provided with outlet valves and is connected with compressed gas source through accumulation vessels. Alarm means are made as infrared sensors and are communicated with control electronic apparatus. Each outlet valve is provided with electric drive connected with control electronic apparatus.

EFFECT: provision of fire extinguishing in the cases, in which water and fire-extinguishing foam usage is impossible, increased reliability and safety of fire suppression under low temperatures, reduced fire-extinguishing system response time and decreased maintenance costs.
