Flow-Accelerated Corrosion (FAC) in Conventional Fossil Units:Cycle Chemistry Influences and Management Approach

摘要

The authors have reviewed flow-accelerated corrosion (FAC) programs used at various types of conventional fossil plants. The results and findings of the assessments are presented and discussed. A number of emergent areas of FAC damage have been added to the previous suite of recognized susceptible locations with a concentration on damage due to two-phase FAC. Several deficiencies related to feedwater chemistry and FAC management approaches were noted to be common among the plants. These characteristics may influence the FAC susceptibility and awareness at other plants.
