The utilization of acoustic waves in fire suppression and prevention

The following paper examines the influence of acoustic waves on the behaviour of flames generated by various fuels. For the purposes of this investigation, a number of experiments were carried out using a specially constructed laboratory stand. This stand consisted of an acoustic waves frequency generator, an amplifier, and a low frequency speaker connected to the channel, upon which the waves were transmitted. The flames generated by various fossil fuels: gasoline, diesel oil and natural gas were exposed to the acoustic waves. The results of the experiment identified the critical sound pressure levels needed to extinguish various types of flames. These results may prove to be useful in the future construction of fire prevention systems at industrial facilities.
