Candidate heat exchanger materials tested in the Low Mass Flow Train at the Coal-Fired Flow Facility (CFFF) at Tullahoma, TN, were analyzed to evaluate their corrosion performances. Tube specimens obtained at each foot of the 14-ft-long U-bend tubes were analyzed for corrosion-scale morphologies, scale thicknesses, and internal penetration depths. Results developed on 1,500- and 2,000-h exposed specimens were correlated with exposure temperature. In addition, deposit materials collected at several locations in the CFFF were analyzed in detail to characterize the chemical and physical properties of the deposits and their influence on corrosion performance of tube materials
