This report is a comprehensive documentation and analysis of utility experience with materials of construction in full-scale lime and limestone wet fluidized gas desulfurization (FGD) systems. Information on field performance of construction materials was collected by site visits, by telephone and letter contacts with FGD system operators and equipment vendors and by literature searches. Information was collected on: prescrubbers, absorbers, spray nozzles, mist eliminators, reheaters, fans, ducts, expansion joints, dampers, stacks, storage silos, ball mills and slakers, pumps, piping and valves, tanks and thickness, agitators and rakes, vacuum filters and centrifuges, and pond linings. Materials documentation and analysis includes successes, failures, reasons for success or failure, failure mechanisms, and relative costs of various materials. The results are designed to aid utilities and FGD equipment suppliers in selecting materials that aid will perform satisfactorily without unnecessary expense. Outlet ducts downstream from the outlet dampers and stack linings have a significant history of materials problems and are critical components - failures may require complete boiler shutdown and loss of generating capacity for lengthy periods. Prescrubbers, absorbers, reheaters, outlet ducts stream of the outlet dampers, dampers, pumps, and piping and valves have a moderate history of materials problems, but failures may not require complete boiler shutdown. Spray nozzles, mist eliminators, fans, inlet and bypass ducts, expansion joints, storage silos, ball mills and slakers, tanks and thickeners, agitators and rakes, vacuum filters and centrifuges, and pond linings have a relatively low history of materials problems and/or are amenable to rapid repair or replacement.
