Water, foam and reagents are the main resources for extinguishing fires, which, however, are extremely harmful to the ecology. Scientists from the USA have proposed the technology of environmentally friendly flame. A whirlwind stream of compressed air with support for ionization is directed to the fire, which should increase turbulence and the force of influence on the fiery element. The technology showed effectiveness in the laboratory. Large -scale trials are just around the corner.

Researchers from the University of Ohio (Ohio State University) knew from personal experience that with proper effort, you could blow up many candles on a festive cake. However, even a weak bonfire will not work out in this way, which was also well known to them. Then the scientists decided to blow out the flame with compressed air, passing it through special nozzles that create turbulence. To enhance the effect, conductive aerosol particles were added to the air flow that could create the effect of ion winds and increase the efficiency of fire extinguishing.
Having sorted out seven different mixtures, the researchers stopped on particles of pure copper. For the experiment, two nozzles for spraying were developed: one – round cone -shaped, the other with a square bell. The spray of particles was installed on top of the nozzle closer to the output, throwing them into the flow of air.

Experiments on the blowing of candles showed that both nozzles cope with the task approximately equally well – they extinguish most of the candles from a distance of two meters. However, to the chagrin of researchers, the nozzles turned out to be effective even without attracting ions, which, however, did not stop publishing work in the journal Technologies. Nevertheless, scientists do not lose hope of creating a more effective and environmentally friendly individual fire extinguishing system, which will reduce the damage from the use of chemical reagents, as is happening today.
