Since the first flue gas desulfurization (FGD) system began operation in the late 1960s, the technology for sulfur dioxide (SO/sub 2/) removal has progressed from an art to a science. Most readers are aware of the problems in the early history of FGD; loss of system availability due to corrosion, scaling, failure of controls, and other causes have been widely publicized. In recent years, closer attention to design details and testing of equipment and materials of construction have contributed to improvements in newer FGD systems. System specifications are no longer directed towards performance only, but now include details of individual items of equipment. A successful FGD system meets environmental regulations (such as SO/sub 2/ and particulate emissions), while minimizing any impacts on operation of the boiler. An FGD system with high reliability meets these criteria on a continuous basis. This paper is a practical discussion of the features which contribute to reliable FGD systems and components. Although most of the information discussed concerns wet limestone FGD systems with sludge stabilization for waste treatment, the concepts of reliability presented are applicable to all FGD technologies.
