Chimneys
BEIRENS designs all types of welded industrial chimneys to suit your operating constraints, fuel (gas, heating oil, heavy fuel oil, wood, coal, biogas or biomass), the type of waste (chlorine, volatile organic compound , metals ...), the number of generators and environmental site (rural, urban). Our chimneys are CE certified and comply with EN 13084 under the directive of construction products 93-68 EEC. Each BEIRENS chimney is a work of art. We pay particular attention to the quality of all our products and to ensuring compliance with the following aspects: standards and legislation, stability, materials, tightness, insulation and finish.

Beirens - Model Gigogne - Concentric Flue Chimneys
Gigogne, or concentric flue, chimneys comprise several nested flue liners of decreasing diameters. The internal flues evacuate fumes from the generators and the shell evacuates fumes and forms the structural shell of the chimney. Gigogne chimneys provide the ideal response to the regulations: «Every effort is made to ensure that the combustion gases are evacuated using the least number of chimneys possible, at a height enabling an effective ...

Exhausts
BEIRENS designs, manufactures and installs smoke flues (or exhaust ducts) for all types of generators: boilers, motors, turbines, ovens and fans. We deploy two technologies: welded and modular (single and double-wall). BEIRENS exhausts are designed to reduce pressure losses, optimise flue draught and evacuation of condensation. The number of cantings is optimized and the 45° angles are favoured.

Beirens - Single and Twin Wall Modular Flue and Chimney System
Our single and twin wall modular flue and chimney systems are suitable for evacuating gases from boilers running on gas, fuel oil, wood and coal. They can be used in many types of applications: ideally suited for domestic, commercial and industrial schemes, the flues can be located internally or externally, and for both new build and renovation ...

Acoustic Treatment
BEIRENS designs, manufactures and installs absorptive and reactive made-to-measure silencers, in line with your requirements and operating conditions in order to treat transmission of noise through outlets or walls of exhausts. They are installed by our specialists, who are trained to work in all types of environments. Our experience in exhaust acoustics also enables us to refurbish existing silencers. Our acousticians can carry out spectral analysis on your site, in particular compliance with environmental constraints bound to the decree of 23rd January 1997. We identify and characterise the source(s) of noise and propose the best adapted solutions for your installation.

Boiler Silencers
Double-chamber resonator: This silencer is formed by assembling two volumes inside a section of the smoke flue (exhaust or chimney) through which all smoke flows. The transversal section of these chambers is greater than the size of the flue, hence the name «expansion chamber». Gas inlets and outlets of these silencers can be axial or ...

Beirens - Turbine Silencers
This type of silencer consists of a series of parallel baffles placed inside the smoke flue (exhaust or chimney) creating large contact areas that efficiently absorb low, medium and high frequency noises. The noise generated by turbine exhausts is significant (>130 dB) and therefore requires high-performance acoustic treatment. Each baffle is optimised to achieve the highest level of performance, while reducing pressure losses as much as possible. ...
