Description: Dooley pointed out that the assessments prove FAC and under-deposit corrosion are global generic HRSG issues. He made the following recommendations for the control of FAC in heat-recovery steam generators: Specify AVT(O) to control single-phase FAC in the feed system.

Description: Leaking of the two HRSG superheater tubes had occurred due to flow assisted corrosion (FAC). The flow from the header into the two inlet tubes had created the conditions leading to FAC and accelerated wall loss. This had caused localized wall loss accounting for up to 80% of the original wall thickness. Once significant thinning had
