Chimney exhaust silencers are primarily used for effective noise reduction of gas emissions in industries such as power, chemical, and metallurgy.
Chimney noise is typically produced by the exhaust of combustion fans, with the noise level reaching above 110 dBA. The noise is predominantly in the mid-to-low frequency range of 200Hz-800Hz, exhibiting a wideband characteristic. Due to the long transmission distance and strong penetration of mid-to-low frequency noise, it poses a significant health impact and is a difficult problem for production units to resolve.
Our Lianyungang Dabao Machinery & Equipment Manufacturing Co., Ltd. has developed exhaust muffler products for gas boiler chimneys through years of design and field application. These are primarily effective for medium and low-frequency noise reduction, with minimal resistance loss.
