Steam Vent Silencer
Engineered noise control solutions for steam systems — designed, manufactured, and installed by ARK Noise Control (India)
Why Steam System Noise Needs Control
Steam venting during boiler start-up, warm-up, and emergency relief generates noise levels of 120-140 dB(A) at the vent outlet. This extremely high noise level is caused by supersonic steam jets expanding to atmosphere, creating intense aerodynamic turbulence and shockwave noise that can be heard several kilometres away.

How ARK Solves Steam System Noise
ARK designs multi-stage steam vent silencers that progressively reduce the steam velocity and turbulence through a combination of diffuser stages, expansion chambers, and absorptive packing. The multi-stage approach breaks the supersonic jet into multiple subsonic jets, dramatically reducing aerodynamic noise while maintaining safe vent discharge operation.
Key Benefits
- Noise reduction of 30 to 40+ dB(A)
- Multi-stage diffuser design for progressive noise reduction
- Designed for high-pressure, high-temperature steam (up to 600°C)
- Corrosion-resistant materials for wet steam environments
- Low backpressure to prevent interference with safety systems
- Field-proven in 200+ power plant installations worldwide
