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. Consolidated Edison Company of New York, Babcock & Wilcox, and Condensing Heat Exchanger Corporation are undertaking an extensive program to develop this technology. This includes a full scale (approximately 30 MW{sub e} equivalent) demonstration at Consolidated Edison`s Ravenswood Station, the site on which a 5 MW{sub e} pilot had been tested previously. This paper summarizes the current status of condensing heat ex-changer and IFGT development activities that are in progress. Details of the demonstration at the Ravenswood Station are included.
