Industrial boiler silencers: noise control and operating performance
In industrial environments, gas or oil-fired boilers are strategic equipment for heat production. However, they generate high levels of noise, dominated by low frequencies that are difficult to control. Without appropriate noise treatment, these nuisances have an impact on regulatory compliance, team comfort and the environmental acceptability of sites.

Introduction
Noise reduction in thermal installations cannot be limited to a simple attenuation device. It calls for a comprehensive approach incorporating industrial acoustic studies, customized design and aeraulic optimization.
The challenge: to ensure effective sound attenuation without compromising energy performance.
The acoustic challenges of industrial boilers
Industrial gas or oil-fired boilers, equipped with forced-air burners and forced-draft systems, produce significant noise levels. The main sources of noise can be high-speed fans and airflows, combustion phenomena, and resonances in exhaust ducts.
These emissions call for industrial acoustic solutions capable of efficiently handling low frequencies, while limiting pressure losses. Inadequate sizing can lead to degraded thermal performance and higher energy consumption.
Noise control is thus part of a global acoustic management approach to reducing noise emissions in industrial environments.
Industrial silencers for boilers: precision acoustic engineering
To meet these requirements, the Groupe BOËT has developed industrial silencers specifically designed for boiler discharge.
Each acoustic silencer is based on :
- Detailed spectral analysis of emissions
- Industrial acoustic studies adapted to actual operating conditions
- Aeraulic modeling to ensure compatibility with existing burners
Depending on the configuration, the silencers incorporate :
- Integrated noise control technologies
- Optimized expansion chambers
- Absorption by high-temperature sound-absorbing materials (concentric long fibers or baffles)
- Anti-resonance systems targeting critical frequencies
- Design compatible with chimney integration
These industrial acoustic devices provide high-performance noise attenuation, without compromising draught or energy efficiency.
The industrial silencers developed for boilers are in line with the Groupe BOËT’s expertise in compressor, booster and engine silencers, with specific adaptation to high thermal constraints.
Measurable performance in noise reduction
An industrial acoustic treatment solution must produce quantifiable results. Industrial silencers designed for boilers provide sound attenuation of up to 60 dB(A). Pressure losses are kept under control, while complying with local and international regulatory requirements.
This acoustic reduction contributes to the acoustic protection of the sites and the reduction of noise pollution for the teams and the immediate environment.
This makes noise control a key factor in operational optimization and social acceptability.
Integration and additional acoustic equipment
In some contexts, noise reduction requires a broader approach combining several acoustic devices.
Depending on the site configuration, solutions may include :
- Acoustic cladding or enclosures
- Acoustic panels and partitions
- Acoustic grilles and acoustic louvers
- Acoustic doors for technical areas
- Sound-absorbing materials (acoustic mineral wool, sound-absorbing panels, soundproofing components)
These industrial acoustic treatment systems provide consistent noise control throughout the plant.
Groupe BOËT expertise in industrial acoustic solutions
The Groupe BOËT has recognized expertise in the design and manufacture of acoustic equipment for demanding industrial environments: energy, process, nuclear, data centers.
The proposed solutions are based on :
- Customized sizing
- Complete control of the value chain, from design to installation
- Robust construction in carbon steel, stainless steel or Inconel, depending on requirements
- ISO 9001 and ISO 19443 certification
- Compliance with EN 15085, EN 13445, EN 13480, ASME, RCC-M, CODAP and CODETI codes
This approach guarantees technical acoustic solutions that are durable, safe and adapted to severe thermal environments.
Conclusion: Secure your heating systems through controlled noise reduction
Noise from industrial boilers is a technical, regulatory and operational issue. Improperly dimensioned noise control can compromise energy performance and site compliance.
Acoustic silencers developed by the Groupe BOËT provide an integrated solution combining sound attenuation, aeraulic optimization and industrial robustness.
