| Summary, etc. |
In recent years, finding quick and environmentally safe ways to put out<br/>flames has taken on particular importance. The acoustic approach to flame<br/>suppression is one of the most promising. Since acoustic waves can travel through<br/>solids, liquids, and gases, they can theoretically be used to put out fires of many<br/>types. The technology mentioned can theoretically be used to put out B-class fires<br/>when gases or liquids are on fire. The investigations that are now available have<br/>only been done with low-power acoustic extinguishers. Therefore, there is a<br/>theoretical and practical void in this area that must be filled. As a result of the<br/>activities, new methods for putting out fires employing high-power loudspeakers<br/>attached to acoustic extinguishers were developed using image processing. The<br/>main goal of this paper is to present the possibilities of using image processing to<br/>detect fires as well as the findings of research on the extinguishing of flames with<br/>the use of sine waveforms with Amplitude Modulation (AM) for several frequencies,<br/>which is also a scientific novelty, including the minimum acoustic power and sound<br/>pressure level as a function of a distance from the output of the acoustic system.<br/>Based on this, it was possible to calculate the minimum power sent to the<br/>extinguisher and the minimum sound pressure level that produces the<br/>extinguishing effect at specified input parameters – class A, B, and K fires. |
