The influence of the start-up procedure on the corrosion behavior of selected stainless steels in supercritical water

Popis výsledku v původním jazyce

In order to enhance overall efficiency of today?s fossil-fuelled power plants the working parameters of the working media ? water ? are increased substantially. Currently the energy industry is focused on units operating up to 600 °C and 27 MPa the conditions under which water is supercritical. There are many advantages in operating such supercritical unit but several drawbacks as well. One of the biggest negative of supercritical water is its high corrosiveness towards commonly used constructional steels. The corrosion resistance of these materials in supercritical water is given by the quality of oxide layer which forms a barrier between the metal surface and the corrosive media and therefore hinders further corrosion of material. In this paper we studied and evaluated the corrosion behaviour of selected both martensitic the austenitic stainless steels in supercritical water. We modified default boiler startup procedure and observed whether it has an impact on corrosion behaviour of
