    Abstract

    Since the passage of the Clean Air Act of 1970, flue gas desulfurization (FGD) or scrubber systems have come into common use in fossil fuel power generation plants. Linings used in such systems must be able to withstand harsh service conditions that include wide fluctuations in temperature; acidic gases; a wide range of contaminants, both organic and inorganic; abrasion from fly ash and limestone slurry; and vibration. The properties of fluorelastomers, a relatively new material for such systems, are explored in detail and compared with four other types of materials used in FGD service: specialized alloys, inorganic monolithic cements, acid-resistant masonry, and other organic coatings.
