Dynamic corrosion testing of metals in solar salt for concentrated solar power
Sutter, Florian; Oskay, Ceyhun; Galetz, Mathias Christian; Cunha Diamantino, Teresa; Pedrosa, Fátima; Figueira, Isabel; Glumm, Stefan; Bonk, AlexanderABSTRACT: Potassium nitrate and sodium nitrate in mixing proportion of KNO3-NaNO3 40-60 wt% (also called solar salt) has been successfully used for over a decade as heat storage medium for concentrated solar power parabolic-trough collector plants at temperatures up to 400 degrees C. At temperatures of 560 degrees C, reached in state-of-the-art solar tower systems, corrosion of metallic components in contact wi...
