Steam exhaustMufflerOperates based on the "micro-hole injection" theory combined with the noise reduction principle of impedance expansion and sound absorption. Due to the high flow velocity and air noise of boiler steam emissions.
Therefore, it is necessary to first conduct perforation expansion. After multiple perforations, the steam undergoes pressure and flow reduction in the resistance expansion chamber. The airflow is then ejected through small holes, where the sound power across different frequency bands has decreased. However, the sound pressure level frequencies are pushed above 20,000 Hz. Although the noise has been significantly reduced, secondary noise at certain frequencies still requires further attenuation. Consequently, we have added a resistive sound-absorbing cotton structure outside the expansion chamber.
The steam exhaust silencer is designed based on the frequency spectrum characteristics of the remaining noise announced by the pressure-reducing unit, making it highly effective in absorbing residual noise. Many users have reported that after installing the steam silencer as required, the noise reduction can reach 30-42 decibels, making it a great helper in noise reduction and silencing.
