... tube failures. The waterwall tube samples were reportedly removed from a coal- and oil-fired Riley Stoker boiler which operates at 2.0 MPa (2900 psig) and 541 °C (1005 °F) (superheater and reheater) on a swing cycle. The boiler, in service for twelve years, was chemically cleaned with acid nine...
