The Roots blower silencer is designed based on the composite noise reduction principle of resistance, injection, and obstruction, featuring large noise reduction, compact size, light weight, and easy installation. The boiler silencer is mainly used for noise reduction during steam boiler ignition exhaust in power plants, thermal power companies, petrochemicals, iron and steel metallurgy, paper printing and dyeing, textiles, mining, and other industrial and mining enterprises. It is also applied to steam safety valve exhaust noise reduction, boiler flushing noise reduction, back-pressure steam turbine exhaust noise reduction, high-pressure deaerator equipment exhaust noise reduction, and noise reduction of steam equipment in the thermal system.
