This report is a comprehensive documentation and analysis of utility experience with materials of construction in full-scale lime/limestone wet FGD systems on boilers burning eastern or western coals. Information was collected for the following FGD system components; 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 thickeners, 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 be a first step in aiding utilities and FGD equipment suppliers in selecting materials that 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 in that failure may require complete boiler shutdown and loss of generating capacity for lengthy periods. Prescrubbers, absorbers, reheaters, outlet ducts upstream 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.
