Abstract
The failures of boiler tubes due to fireside corrosion in a waste heat recovery boiler utilizing the exhaust gas of a gas turbine fired with high-speed diesel has been analyzed. Deposits from the various zones of the boiler were collected and characterized by chemical analysis, scanning electron microscopy and X-ray diffraction. Thermodynamic modeling studies were carried out to study the interaction of the flue gas with the various components of the boiler. The high corrosion propensity and consequent failures in the low temperature sections of the boiler were found to be directly related to the formation of hydrated ferric sulfate in these regions.
