This report is the third in a series of four issues generated by a new computerized data base system. This is an updated supplement to the December 1978-January 1979 report (EPA-600/7-79-022c) and should be used in conjunction with it. This report differs from those of the previous series in that the scope of design data for operating FGD systems is vastly expanded, section formats are revised somewhat and a new section includes operational particulate scrubbers. The report presents a survey of utility flue gas desulfurization (FGD) systems in the U.S. It summarizes information contributed by the utility industry, process suppliers, regulatory agencies, and consulting engineering firms. Systems are tabulated alphabetically by development status (operational, under construction, or in planning stages), utility company, process supplier, process waste disposal practice and regulatory class. It presents data on system design, fuel sulfur content, operating history, and actual performance. It includes unit by unit dependability parameters and discusses problems and solutions associated with the boilers and FGD systems. Process flow diagrams and FGD system economic data are appended to the report.
