Atmospheric steam silencers are designed to cut the noise generated by the expansion of steam from an elevated pressure to atmospheric pressure. The noise produced is a combination of ‘shock noise’ generated by the rapid reduction in pressure across the relief device and the noise created by the turbulent flow of steam downstream.
Where they are applied
Steam silencers are used in areas where it is necessary to:
- Reduce work place noise levels to a desired occupational limit
- Cut the intrusion of industrial noise into residential areas.
Steam silencers are used to suppress the noise generated by safety relief valves, process vents, dumping steam to atmosphere during compressor or boiler set-up sequences, de-pressurising lines for maintenance, ejector discharges and steam exhausts, and the blow down of pipelines for cleaning purposes.
