The report is the second in a series of four generated by a new computerized data base system. The report differs from the previous series in that the scope of design data for operating FGD systems is vastly expanded, section formats are revised, and a new section includes operating particulate scrubbers. The report surveys utility 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 (operating, 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.
