A highly reliable system design involves specifying reliable control, electrical, mechanical, and structural features. Because FGD systems are chemical plants, the care and planning that goes into designing a chemical plant should be a model for future FGD systems. This discussion is limited to a typical wet limestone FGD system with sludge stabilization for waste treatment, but these concepts also apply to other FGD technologies. Equipment that has been the cause of repeated problems in power plant FGD systems and features that improve their operation and maintenance is described. Forced outages and other expensive problems can be eliminated, or at least reduced, in power plant flue gas desulfurization (FGD) systems. This is accomplished through proper design, construction, operation, and maintenance. Early FGD systems frequently faced loss of availability caused by corrosion, scaling, control and mechanical equipment failures, and other problems. In recent years, closer attention to design details and testing of equipment and materials has led to improved systems. Systems specifications are no longer directed toward performance only; the days of the black box FGD system are over.
