Thermo-physical properties of a steel-making by-product to be used as thermal energy storage material in a packed-bed system
-
-
Conclusion
- The results have revealed that EAF slag is thermally stable at least, up to 1000ºC. Moreover, thermo-physical properties measured in this work have shown appropriate values to be used as heat storage material.
- A computational parametric study of a storage device working in air-slag packed-bed arrangement has been performed in the potential temperature range of new generation CSP plants.
-
Introduction
- Heat capacity is determined by Differential Scanning Calorimeter (DSC) and, the thermal conductivity (k).
Definition
- Thermal energy storage (TES) is a key issue in concentrated solar power (CSP) plants in order to increase the global efficiency of the electricity generation process.
Cooling rate
- cooled rapidly by using water (EAF Slag 1) in a process that takes place in 3-4 hours
- cooled in open air during 2-3 days (EAF Slag 2).
