Beirens - Steel Lining and Lining Chimneys

• Easy to implement
• Saves money compared with creating a new chimney
• Keeps the existing structure
• Effective and long-lasting
• Adapted to the existing structure

Insulated tightness at chimney head
With a view to making the existing chimney more reliable, we install a watertight plate in stainless steel 1.4404 (316L) to cover the outside of the old flue. This protects the inner wall of the brick flue from acid flowing down in rainwater and ensures natural ventilation.

• Tightness reading and watertight plate in stainless steel 1.4404 (316L) ensures guidance, free expansion and
  ventilation of the flue
• Smoke flue insulated with mineral wool, density 80kg/m3, thickness 50mm
• Chimney termination seal in stainless steel 1.4404 (316L)
• Stainless steel smoke flue (welded by tight connections) insulated by an air gap (between the brick shell and the
  smoke flue)
• Condensation collection base
• Straight base reinforcements
• Inspection door

• Lightning conductor system: stainless steel rods comply with local regulations with “crow’s foot” earth connection,
  copper plate outside heat insulation and lightning meters
• Fall arrest system ladder compliant with NF EN 353-1, fixed hoop ladder with landings or offset flights (height
  between two landings to 6m according to NFE 85-016 and ISO 14122-4, height between 2 platforms, so a single
  section to 8m according to NFE 85-016 and to 10m according to ISO 14122-4). Specific compliance on demand.
• Inspection platform and work platform compliant with NFE 85-014 or ISO 14122-2. Specific compliance on
  demand.
• Access door(s) and passage(s)
• Weighted index measuring point EN 13 284 2
• Continuous measuring points
• Internal lighting: connection at the chimney base
• Aircraft warning day-time marking: with paint red and white stripes
• Aircraft warning night-time marking: high-intensity duty/standby lamps to be supplied from chimney base
• Acoustic treatment by beirens: absorptive silencers (bulbs, baffles, absorbent wall), reactive silencers (single
  chamber, double-chamber, wave resonators)
• Vibration loading treatment: lining damper cushion
