The failure of two superheater tubes (T1 & T2) is analyzed in the present investigation. The tubes are fractured perpendicular to tube length and bowed down towards the fire side without any brittleness, as examined through naked eye as well as tensile testing. There is no material loss from inside of tubes. Outer surface wall is thinned down by erosion and corrosion mechanism through fly ash deposits. Subsequently, the non-linear heating leads the catastrophic failure after short service period.
