Conclusions Steel slag and the modified steel slag with sodium carbonate were studied as thermal energy storage materials. Sodium carbonate modification is shown an effective route to significantly improve the thermal performance. The following conclusions were drawn after a series of morphology analysis and thermal performance tests.
The thermal energy storage density reaches 997.0 kJ·kg −1 (400–900 °C), which is 25.3% higher than original steel slag. Even more, the thermal conductivity is 1.331, 1.323, 0.889 W· (m·K) −1 at 25, 250, and 500 °C, respectively, which is 32.7% higher than that of steel slag.
The following conclusions were drawn after a series of morphology analysis and thermal performance tests. The main components of steel slag are oxides of Ca, Si, Mg and Al, and the main phase of sintered steel slag heat storage material is calcium-aluminum-feldspar. The steel slag heat storage material has excellent thermal cycle stability.
The thermal stability and compatibility of steel slag with synthetic oil, solar salt and air in direct contact were analyzed, and a prototype of 400 kWh·T −1 steel slag-based packed bed heat storage was carried out, which provided technical support for large-scale industrial application.
Agalit et al. (2017, 2020a; 2020b) focused on an induction steel slag and found that the sample slag has a specific heat capacity of about 0.7 kJ· (kg·K) −1 and a density of nearly 2583 kg·m −3, and has great potential in high temperature (1000 °C) heat storage applications.
At present, most researches on SHS materials are on electric arc furnace steel slag (Agalit et al., 2017, 2020a, 2020b; Ortega-Fernández et al., 2015, 2018, 2019; Wang et al., 2018), and it can be found that the SHS materials prepared have low thermal conductivity and specific heat capacity.
