- ItemParametric analysis of a modular solar drying and packed bed thermal energy storage system(2025) Wolde Ponce, Ian; Calderon Vasquez, Ignacio Andres; Molina, Matias; Pailahueque, Nicolas; Cardemil Iglesias, Jose MiguelSolar drying is an effective technology for reducing fossil fuel consumption in food preservation. However, its reliability is limited by the availability of solar radiation. Integrating thermal energy storage (TES) can enhance system efficiency by extending operation beyond peak sunlight hours. The use of industrial by-products with high thermal capacities, such as metallurgical slags, offers a promising alternative for TES. However, the integration of solar collectors and TES remains a challenge, as system performance depends on the configuration and operational strategy. This study presents a parametric analysis of a solar drying system for kiwifruit slices, incorporating solar air collectors and a packed-bed TES unit. A validated mathematical model, supported by experimental data, is used to assess three different schemes for discharging TES, considering flow-switching strategies, six solar field configurations, and the role of an auxiliary heater in maintaining drying reliability throughout the year. The findings indicate that early switching the airflow, combined with smaller TES volumes and one solar collector, achieves a 40.53% cost reduction compared to a conventional drying configuration. The results highlight that balancing the system’s components significantly enhances solar drying performance.

- ItemThe Effect of Long-Term Corrosion on a Molten Salt Pump in Contact With a Ternary Mixture in a CSP Plant(2024) Mauro Henriquez; Carlos Francisco Soto Soto; CARLOS DANIEL DURAN MORA; Sebastián Salazar Avalos; Felipe M. Galleguillos Madrid; Luis Guerreiro; Douglas Olivares; Carlos Portillo; Edward Fuentealba; Cardemil Iglesias, Jose MiguelSolar thermal plants commonly plan their operation for a period of approximately 25 years. Therefore, it is key to accurately predict and evaluate the damage and faults occurring for that long period. Among all components, we find that choosing the heat storage medium (molten salt) and the material (steel) used in the equipment and pipping plays a crucial role in the plant’s design. We tested the long-term corrosion effect of the molten salt pump in a low-melting-point ternary mixture composed of 30wt.%LiNO3+57wt.%KNO3+13wt.%NaNO3 over a period of more than 5 years, corresponding to 30,000 hours of operation in a pilot experimental facility built at the University of Antofagasta (Chile).
