New Chimney Design
Tomorrow’s chimney design: lighter, cheaper, built to last
Faster and less expensive to build
The New Chimney Design chimney has several advantages compared to a traditional chimney with a reinforced concrete windshield and a separate internal flue. The New Chimney Design is more economical to build, because two expensive items, the internal liner and its supports, have been eliminated. The construction time is shorter; building the chimney consists of slipforming the concrete column directly followed by installation of the PennguardTM chimney lining.
Lower maintenance and exellent chemical resistance
The New Chimney Design has lower maintenance requirements, because the chimney flue, the flue supports, insulation and expansion joints have all been eliminated. The New Chimney Design is resistant to a wide range of operating conditions (including FGD operation). The PennguardTM lining is completely acid resistant without limitations for temperature or concentration. The New Chimney Design has greater suitability for seismic regions. The elimination of an internal flue leads to a great reduction in mass, which is favourable when designing a chimney for seismic conditions (see Project Report Colbun & Bocamina Power Stations).
It can be economical to build several New Chimney Design chimneys instead of one multi-flue chimney
