摘要：

A variety of works have been performed at the Evora Molten Salt Platform on a new collector system especially designed for optimised operation with solar salt as well as tests on a ternary salt. Concerning the new HelioTrough (R) 3.1 design the paper discusses how 30% less specific mass could be reached. Together with a novel approach to "run-in" bearings, as to lower friction, the torsion could be reduced significantly. Resultingly costs were reduced while improving precision of the trough. The ternary salt has been operated between October 2021 and May 2022 in the end reaching operation temperatures up to 500 degrees C. Samples have been taken and analysed to investigate nitrite and nitrate development amongst others. The heat capacity of the Yara Molten Salt has been determined with now a high level of precision, as well as the density.
