The prime requirement for a vent silencer is its ability to handle with total reliability
the rapid release of large quantities of steam from high pressure to atmosphere
and attenuating high levels of noise generated at the vent for steam at wide range
of pressure and temperature conditions. The silencers are made out of concentric
annular acoustic cylinders enclosed with a robust steel casing with dished end or
flat end at one end.
The fluid enters through the diffuser and passes through the annular space between
the acoustic packing where the sound energy is absorbed. The straight flow path
through the annular acoustic cylinders ensure minimum pressure drop. A weather cowl
for rain protection is available as an optional item.
