Rökkanaler

Rökkanaler are conduits designed to convey smoke and combustion gases from a fire source to the exterior or to a dedicated smoke extraction system. They are an essential part of fire safety in buildings, helping to remove smoke from occupied spaces and maintain tenable conditions during a fire.

Rökkanaler can be found in several forms. In private homes, they are typically masonry chimneys or metal flues connected to fireplaces, stoves, or boilers. In larger buildings, rökkanaler may be vertical shafts or lined ducts integrated into the building’s fire protection and smoke control systems. Industrial settings may use larger rökkanaler to evacuate smoke and hot gases from furnaces, ovens, or process equipment.

Construction and design emphasize fire resistance and containment. Rökkanaler are often built with fire-rated linings or metal ducts, insulated to withstand high temperatures, and separated from normal ventilation to prevent backflow of smoke. Joints and connections are designed to minimize leaks, and the system may include dampers, access doors, and cleanouts for inspection and maintenance.

Regulatory guidance for rökkanaler varies by country and local codes. Requirements typically cover fire resistance ratings, proper sizing, separation from combustible materials, and the integration with smoke control and ventilation systems. Regular maintenance is important to remove soot and creosote, ensure integrity of the lining, and verify that dampers and fans operate correctly.

In operation, rökkanaler function as part of a broader fire protection strategy, working in concert with detectors, alarms, and mechanical smoke extraction to limit smoke spread and protect life and property.
