Abstract
A cyclic reheat system for a wet flue gas desulfurization system extracts heat from the inlet flue gas and transfers this heat to the outlet flue gas. One method of achieving this uses tube-type heat exchangers in the inlet and outlet gas streams with a fluid (e.g., water) circulated between them. For high sulfur coal, questions of material selection and cleaning methods for the inlet heat exchanger exist because of the potential for acid condensation. An inlet gas heat exchanger test apparatus was built and installed on a slipstream from a high sulfur coal fired power plant. Results obtained from the first 3061 hours of exposure indicate low corrosion rates for several stainless steels and that a water wash prevented tube solids buildup.
