The report presents detailed technical information concerning application of flue gas desulfurization (FGD) systems to industrial boilers. Design and operation data has been obtained from 152 separate FGD control systems, with a capacity of 8.3 million acfm (2200 MW equivalent). An average of more than six FGD units per year have come on line since 1972, indicating FGD to be a viable method of controlling SO2 emissions. The information was obtained by a survey of plant personnel, control system vendors, regulatory agencies, and consulting engineering firms. The data is given in two types of tables: one gives summary information; the other, detailed information. Summary tables present information as a function of control process, control system vendor, disposal techniques, operation status, start-up date, and flue gas capacity. Detailed information includes: control system design, economics, operating experience, problems and solutions, waste disposal techniques, and maintenance practices.
