Abstract

In this study failure of a high pressure economizer tube of a boiler used in gasMazut combined cycle power plants was studied Failure analysis of the tube was accomplished by taking into account visual inspection thickness measurement and hardness testing as well as microstructural observations using scanning electron microscopy SEM energy dispersive spectroscopy EDS and xray diffraction XRD Optical microscopy images indicate that there is no phase transformation during service and ferritepearlite remained The results of XRD also revealed Iron sulfate FeSO4 and Iron hydroxide sulfate FeOHSO4 phases formed on the steel surface A considerable amount of Sulfur was also detected on the outer surface of the tube by EDS analysis Dewpoint corrosion was found to be the principal reason for the failure of the examined tube while it has been left outofservice
