In-situ Observation of Initial Corrosion Behavior in Molten Salt Environment

Abstract

In order to realize a sustainable and safe society, expansion of the use of biomass fuels in coal power plants is considered. Given the elevated concentration of chlorine and heavy metals in biomass fuels, there is a concern that the corrosion effect of these fuels on equipment may be more considerable than that of coal fuels. In this report, we developed a test method to visualize the initial reaction of corrosion by molten salt containing Zn using a glass cell. We attempted to analyze the corrosion mechanism by direct observation of the salt molten behavior using the developed test method and analysis of reaction products after the test.
