The rotary whistle acoustic ash-cleaning system works by using high-speed compressed airflow. A motor-driven rotating disc cuts the high-pressure air stream and repeatedly opens and closes the air outlet, converting the airflow from direct flow into alternating pulsation, thereby generating high-intensity sound waves.

Key Technical Features • High acoustic output, with sound pressure levels of up to 155 dB or higher, and low-frequency sound waves. • Incorporates a rotating drive mechanism that cuts the high-speed airflow to produce acoustic vibration and generate sound waves.
