Gas side corrosion affects all heat recovery steam generators (HRSGs). Consequences range from unsightliness and reduced performanceto reliability problems and potential safety hazards. The enamel coating used for the HRSG fin tubes was visually and microscopicallyinspected, analyzed and compared with original one. From the results of the analysis, there was not much different between thecoating and the original in the comparison of the strength, SEM (scanning electron microscope), and thermal expansion. For the overallheat transfer due to the coating, it was found that the coating fin tubes have about 2% degradation in comparison with the original ones. However, the use of enamel coating can help strongly to delay the corrosion problem by flue gases in the HRSG.
