Abstract

Abstract Flame extinguishing methods that are safe for humans and non-invasive to the surrounding environment are being sought worldwide. One of them is acoustic technology, which appears to be an innovative and non-invasive means for flame extinguishing. A highpower and long-range extinguisher was built to explore the possibility of using this environmentally friendly technology. The article includes experimental results, obtained from a laboratory stand, on the possibility of extinguishing flames using amplitude-modulated waves depending on the frequency of the acoustic wave and the distance of the flame source from the extinguisher outlet, which is a scientific novelty. The advantages and disadvantages of acoustic technology are also analysed. The paper concludes that low-frequency acoustic waves are favourable for extinguishing flames because they cause more turbulence in the flame, and thus have a higher extinguishing efficiency. The results are promising and acoustic waves may be used to successfully extinguish flames in a wide range of firefighting scenarios in the future.

调幅波灭火实验研究——以声环保技术为例

摘要在世界范围内，人们一直在寻求对人类安全且对周围环境无创的灭火方法。其中之一是声学技术，这似乎是一种创新的、非侵入性的灭火手段。为了探索使用这种环保技术的可能性，建造了一个大功率和远程灭火器。这篇文章包括从实验室台获得的关于利用调幅波扑灭火焰的可能性的实验结果，这取决于声波的频率和火源与灭火器出口的距离，这是一个科学的新奇事物。分析了声学技术的优缺点。本文的结论是，低频声波有利于灭火，因为它们在火焰中引起更多的湍流，从而具有更高的灭火效率。结果是有希望的，声波可以在未来广泛的消防场景中成功地用于扑灭火焰。
