Condensing heat exchangers recover both sensible and latent heat from flue gases. Using Teflon{reg_sign} to cover the heat exchanger tubes and inside surfaces that are exposed to the flue gas ensures adequate material lifetime in the corrosive environment encountered when the flue gas temperature drops below the acid dew point. A recent design improvement, called the integrated flue gas treatment (IFGT) concept, offers the ability to remove pollutants from the flue gas, as well as recover waste heat. It has been shown to remove SO{sub 2}, SO{sub 3}, particulates, and trace emissions. Babcock and Wilcox (B and W) is undertaking an extensive program to optimize this technology for a variety of flue gas applications. This paper summarizes the current status of IFGT technology and the development activities that are in progress.
