Pollution, noise and vibrations: inseparable phenomena

When an internal combustion engine is running, several effects occur simultaneously:
– NOx, CO and particulate emissions linked to combustion;
– aerodynamic and mechanical exhaust noise;
– significant rise in gas temperatures;
– transmission of vibrations to surrounding structures.

These phenomena are highly interdependent. A modification aimed solely at reducing noise can lead to increased pressure loss, degraded engine performance or increased vibration. Conversely, a poorly-integrated pollution control system may increase temperatures or noise levels.

This is why the exhaust system must be designed as a coherent technical system, not as a juxtaposition of independent components.

The requirements of industrial and energy operators

Today’s operators expect solutions capable of simultaneously meeting several objectives:
– sustainable compliance with environmental and acoustic standards;
– high reliability, even in intermittent or emergency operation;
– compactness for integration in confined spaces;
– reduced overall installation and operating costs.

These requirements apply to both industrial sites and sensitive energy facilities, which are subject to strict regulatory constraints and service continuity imperatives.

The complete Groupe BOËT exhaust system

To meet these challenges, the Groupe Boët has developed a complete complete exhaust systemdesigned from the outset as an integrated system. This solution is based on in-house engineering expertise in all key disciplines: acoustics, aeraulics, thermics, vibration and pollution control.

A coherent, global architecture

The complete Groupe BOËT exhaust system combines :
– high-efficiency catalysts to reduce pollutant emissions;
– optimized acoustic silencers, adapted to the engine’s dominant frequencies;
– thermal and vibration management devices;
– an exhaust pipe sized to preserve the engine’s overall performance.

Each component is designed and dimensioned in interaction with the others, to optimize the system as a whole.

Measured performance and operating benefits

Thanks to this system approach, the Groupe BOËT’s complete exhaust system delivers high, measurable performance:
– up to 98% NOx reduction, depending on configuration ;
– up to 60 dB of acoustic attenuation;
– controlled management of vibrations and thermal stresses;
– optimized load losses, guaranteeing motor efficiency.

A compact, easy-to-integrate solution

Designed to be compact, modular and plug & play, the solution integrates easily, even in environments with severe space constraints or high operational requirements. This compactness means fewer structural adaptations and shorter installation times.

Lower overall costs and greater reliability

By choosing an integrated exhaust system, operators benefit from :
– optimized size and weight;
– enhanced reliability, thanks to the system’s overall consistency;
– simplified installation and maintenance;
– sustainable compliance with environmental regulations.

Groupe Boët solutions are based on demanding quality and safety standards, attested by ISO 9001 and ISO 19443 certifications, as well as EN 15085, ASME, RCC-M, CODAP and CODETI construction codes.

A systems approach to sustainability

Groupe BOËT’s complete exhaust system illustrates the importance of a global approach to simultaneously controlling pollution, noise, heat and vibration. By integrating all constraints right from the design stage, this solution reconciles environmental performance, industrial reliability and economic optimization.

It is aimed at operators wishing to ensure the long-term safety of their facilities, while meeting the most stringent regulatory requirements and the challenges of long-term performance.
