COMBINED FIRE EXTINGUISHING SYSTEM BASED ON THE SHOCK WAVE AND THE GAS VOLUME OF THE EXTINGUISHING AGENT

Abstract

The article is theoretically proved and experimentally confirmed that the combined fireextinguishing system on the basis of the shock wave and the gas volume of the extinguishing agent have significant fire-fighting efficiency. It was established experimentally that the effect of shock waves with a frequency of 10-12 Hz reduces the minimum extinguishing concentration to 4.8%. and nitrogen to 10.2% vol., with the power of WOW about 170 PA. It is proved that the action of the gas fire extinguishing substances under the influence of the WOW series has a complex synergistic effect, which is manifested in the reduction of volumetric fire extinguishing concentration of CO2 and N2 up to 50% of its original value.
