The paper summarises progress on an Electric Power Research Institute (EPRI) sponsored program to investigate the applicability of advanced electrochemical techniques for on-line monitoring of corrosion in flue gas desulfurization (FGD) systems. The approach has combined technology previously developed in England for studying acid dewpoint corrosion with the on-going American research into the causes of corrosion damage in FGD systems. As a first step, the monitoring system has been tested at the LaQue Center for Corrosion Technology (LCCT) at Wrightsville Beach, NC, and the R.M. Schahfer Generating Station of the Northern Indiana Public Service Company (NIPSCO), Wheatfield, Indiana. Initial results are encouraging, in particular, variations in scrubber operation and their effects on materials corrosion behavior have been studied. Some typical data obtained during the program is presented and the prospects for future developments are reviewed.
