Abstract

Elektrárny Opatovice a.s. decided to refurbish its Opatovice power plant with new wet limestone FGD systems, to eliminate its reheat system and to operate wet stack. It was also decided that the existing concrete chimney with sectional brick flue would be re-used. The owner chose PennguardTM linings to seal the complete brick flue to protect it against the highly acidic flue gas condensate. Alden Research Laboratory performed a detailed flow model study with recommendations for Opatovice Power Station to achieve environmentally acceptable wet stack operation.
