Rural and urban free-standing chimneys

Beirens designs all types of free-standing stacks to suit its clients’ operating appliance and site environment requirements, for both rural and urban purposes. These chimneys are suitable for all types of fuel, including gas, heating oil, heavy fuel oil, biogas and biomass, as well as many different types of waste.

Beirens’ chimneys conform to the EN 13084 standard in application of the 93-68 EEC directive on construction products, as well as other standards if required. Ceric, the company’s group research laboratory, has carried out tests with a view to CE marking.

Beirens considers every chimney to be a work of art. The company pays particular attention to the quality of each one of its products, while ensuring compliance with the following rules:

  • Full understanding of and compliance with legislation in force
  • Appropriate types of stability
  • Choice of materials
  • Stack inlet at 135°
  • 316L stainless-steel chimney terminals
  • Guaranteed watertight insulation
  • High-performance insulation
  • Fine finishes
  • Reinforced chimney bases

Exhaust ducts and horizontal flues for generators

Beirens designs, manufactures and installs exhaust ducts or horizontal flues for a wide range of generators, including boilers, motors, turbines, furnaces and ventilators. To achieve this, the company makes use of two technologies: welded and modular (single and double inner walls).

All horizontal flues are designed to optimise pressure loss and smoke duct, while elbows are optimised with 45° angles preferred. Beirens’ horizontal flues are guaranteed to ensure safety of installation, as well as sound structural resistance. Thanks to continuous welding, Beirens horizontal exhausts are 100% watertight, as well as being manufactured in full compliance with legislation in force.

Vibratory and acoustic treatment

Beirens designs, manufactures and installs absorbent and reactive made-to-measure silencers, in line with customers’ requirements and operating conditions. The company’s acousticians can carry out spectral analysis of your site and propose innovative solutions adapted to all circumstances.

To provide answers to structural problems resulting from vibration, fatigue and wear, Beirens has come up with a dynamic vibration absorber, with installation carried out by specialists trained to work in all types of environment. The company carries out repair of different types of existing silencers, with or without on-site maintenance.

Standardised and made-to-measure accessories

Beirens manufactures a wide range of standardised and made-to-measure equipment for existing applications and new buildings. Use of such accessories is determined by technical constraints, legal and operational requirements, including:

  • Standard inspection platform
  • Ladder and landing
  • Explosion relief valve
  • Anti-vacuum
  • Drain and condensation points
  • Stainless-steel expansion joints
  • Flexible sleeving
