Beirens - Single-Flue Chimneys
From Chimneys
Single-flue chimneys are single-wall metal industrial chimneys intended for boilers, electricity generators, turbines and furnaces running on gas, heating oil, heavy fuel oil, wood, coal, biogas or biomass. The smoke flue ensures both the stability of the chimney and smoke evacuation. Our extensive choice of materials means that Single-flue chimneys can be adapted to evacuate all types of waste. The smoke temperature can reach 1,200°C and more. Single-flue chimneys can be tied, free-standing or guy wired. They can be adapted to all types of height and diameter to suit your operating appliance requirements..

Specific Technical Features
Chimney termination seal
The flue termination is a sensitive part of the chimney as it is subject to the acidic condensation of the combustion gases. All of our chimney terminations are therefore made out of austenitic stainless steel 1.4404 (316L). This protection makes the external insulation (mineral wool) tight, whatever the expansion conditions..
Inspection door
Our easy-to-dismantle inspection door enable you to access and inspect the chimney during maintenance. They come in 150 x 250mm, 250 x 250mm or 400 x 500mm sizes (contact us for made-to-measure hatches). BEIRENS inspection door can come insulated against heat as an option.
