| Resumen | Transcripción del resumen del autor. It is of great importance nowadays to develop a deeper understanding of corrosion phenomena occurring in energy conversion processes in thermal power plant technology systems. The superheaters in biofuels and waste-firing boilers are often exposed to aggressive compounds, which strongly decrease their durability. Waste incinerators and demolition wood-fired boiler deposits usually contain relatively high concentrations of heavy metals, such as Zn and Pb compounds. These elements, in combination with chlorine, can decrease the first melting point of the deposits. Consequently, molten salt attack by these metal chlorides can occur, and the corrosion will be more severe than gas-phase corrosion. In this study, laboratory-scale, high-temperature corrosion tests have been carried out. Well-characterized salt mixtures consisting of zinc and potassium chlorides and sulfates (K2SO4, KCl, and ZnCl2) were used for corrosion testing. Tests were performed for three commercially used steam tube materials. The metal specimens covered with salts were exposed to temperatures ranging from 350 to 600 °C for 168 h. After heat treatment, the specimens were analyzed using a scanning electron microscope and energy-dispersive X-ray (SEM-EDX) to determine the oxide layer thickness and the elemental distribution in the oxide scale. The results showed enhanced corrosion of low alloy steel with an increasing temperature and increasing amount of ZnCl2 in the salt mixture. |
