dc.description.abstract | Parabolic trough collector (PTC) technology is currently the most mature solar technology,
which has led to the accumulation of relevant operational experience. The overall performance and
e ciency of these plants depends on several components, and the heat transfer fluid (HTF) is one
of the most important ones. Using molten salts as HTFs has the advantage of being able to work at
higher temperatures, but it also has the disadvantage of the potential freezing of the HTF in pipes
and components. This paper models and evaluates two methods of freeze recovery, which is needed
for this HTF system design: Heat tracing in pipes and components, and impedance melting in the
solar field. The model is used to compare the parasitic consumption in three molten salts mixtures,
namely Solar Salt, HiTec, and HiTec XL, and the feasibility of this system in a freezing event. After
the investigation of each of these subsystems, it was concluded that freeze recovery for a molten salt
plant is possible. | es |
