Degradation examinations of outer surface of evaporator tubes of the OP-230 low-emission steam boiler are presented in the paper. Metallographic evaluation of scale morphology, its micro sites chemical composition analysis and linear distribution of elements on cross sections have been performed. Evaluation of chemical compounds existed in deposited layer was also in-vestigated. Sulfide corrosion bas been aimed as the main reason of premature thinning of evaporator tube walls at lower levels of combustion chamber, and molten salt corrosion at highest levels.
