Recovery Boiler Stacks & Chimneys

Recovery boiler chimneys are exposed to a wide range of chemistry and temperature fluctuations due to the various fuels burned in the recovery process. These fuels include an assortment of liquors, bark, wood chips and other biomass – resulting in acid/alkali condensate at temperatures up to 350F.

Our chemically-resistant gunite linings, polymer linings and acid brick mortars provide long-term protection for your chimney’s interior.
