Case Study: Power Station Chimney Flues
The flues were shop fabricated and trucked to the plant site in 12.2 meter (40 feet) sections and joined in place by field crews.
Due to the size, elevation and exposure of the flues, wind and seismic loading were important factors considered in the design. The flues were designed for wind speeds 120 kilometers (80 miles) per hour. The flues are supported 21.6 meters (71 feet) from their top by an anchor system, with bumpers at several points within the chimney below their primary support point. The top 21.6 meters (71 feet) of the flues are free standing, with one bump point 6.1 meters (20 feet) up from the anchor.
