The understanding of the nature, mechanism, and related factors can help reduce the degradation process caused by corrosion. The chlorine content in the fuel has a significant effect on the production of gaseous components (e.g., HCl) and condensed phases on the chloride base. This study aimed to analyze the effects of flue gases on the outer surface and saturated steam on the inner surface of the evaporator tube. The influence of gaseous chlorides and sulfates or their deposits on the course and intensity of corrosion was observed. The salt melts reacted with the steel surface facing the flue gas flow and increased the thickness of the oxide layer up to a maximum of 30 mm. On the surface not facing the flue gas flow, they disrupted the corrosive layer, reduced its adhesion, and exposed the metal surface. Beneath the massive deposits, a local overheating of the inner surface of the evaporator tubes occurred, which resulted in the release of the protective magnetite layer from the surface. Ash deposits reduce the boiler\u2019s thermal efficiency because they act as a thermal resistor for heat transfer between the flue gases and the working medium in the pipes. The effect of insufficient feedwater treatment was evinced in the presence of mineral salts in the corrosion layer on the inner surface of the tube.<\/jats:p>","DOI":"10.3390\/ma14143860","type":"journal-article","created":{"date-parts":[[2021,7,12]],"date-time":"2021-07-12T00:23:36Z","timestamp":1626049416000},"page":"3860","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Effect of Flue Gases\u2019 Corrosive Components on the Degradation Process of Evaporator Tubes"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9438-9413","authenticated-orcid":false,"given":"M\u00e1ria","family":"Hagarov\u00e1","sequence":"first","affiliation":[{"name":"Institute of Materials and Quality Engineering, Faculty of Materials, Metallurgy and Recycling, Technical University of Ko\u0161ice, 04200 Ko\u0161ice, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3585-2572","authenticated-orcid":false,"given":"Milan","family":"Va\u0161ko","sequence":"additional","affiliation":[{"name":"Department of Applied Mechanics, Faculty of Mechanical Engineering, University of \u017dilina, 01026 \u017dilina, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7101-0957","authenticated-orcid":false,"given":"Miroslav","family":"P\u00e1stor","sequence":"additional","affiliation":[{"name":"Department of Applied Mechanics and Mechanical Engineering, Faculty of Mechanical Engineering, Technical University of Ko\u0161ice, 04200 Ko\u0161ice, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2689-5247","authenticated-orcid":false,"given":"Gabriela","family":"Baranov\u00e1","sequence":"additional","affiliation":[{"name":"Institute of Materials and Quality Engineering, Faculty of Materials, Metallurgy and Recycling, Technical University of Ko\u0161ice, 04200 Ko\u0161ice, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4734-7429","authenticated-orcid":false,"given":"Milo\u0161","family":"Matvija","sequence":"additional","affiliation":[{"name":"Institute of Materials and Quality Engineering, Faculty of Materials, Metallurgy and Recycling, Technical University of Ko\u0161ice, 04200 Ko\u0161ice, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Dziku\u0107, M., Kury\u0142o, P., Dudziak, R., Szufa, S., Dziku\u0107, M., and Godzisz, K.
