Abstract

Fires and conflagrations at thermal power facilities pose a serious threat that can lead to significant economic losses and disruption of the country’s energy supply. Traditional methods of fire reconnaissance using a track rope are time-consuming in conditions of reduced visibility, complex space- planning solutions and a potential threat of roof collapse. A solution to this problem can be ultrasonic devices that are effective in conditions of limited visibility, the principle of operation of which is based on the ability of sound waves to propagate in conditions of smoke and limited visibility. It has been shown that ultrasonic systems are capable of detecting fires at early stages, promptly transmitting alarm signals and, most importantly, generating ultrasonic waves that affect the flame, destroying its structure and helping to extinguish the fire without the use of water or other traditional means. The introduction of ultrasonic technology will improve the safety of gas and smoke protection workers and the efficiency of rescuing victims, minimizing the time spent in the danger zone and reducing the likelihood of serious injury or poisoning by combustion products
