Utilization of foundry waste for thermal energy storage applications

Popis výsledku v původním jazyce

The increasing demand for efficient and sustainable thermal energy storage (TES) systems has highlighted the potential of secondary raw materials as viable alternatives to conventional storage media. This study investigates the physical and thermal properties of selected foundry waste materials specifically waste sand, furnace dust, refractory concrete, slag from furnaces, extraction system dust, and casting molds from cores with the aim of assessing their suitability for high-temperature sensible heat storage up to 800 °C. The materials were characterized in terms of particle size distribution, bulk density (loose and tapped), thermal conductivity, specific heat capacity, and thermal stability. The results indicate that furnace slag and refractory concrete exhibit superior thermal performance, high bulk densities, and minimal mass loss upon heating, making them promising candidates for thermal storage applications. In contrast, materials such as waste sand and extraction dust, despite their fine particle sizes, showed lower thermal conductivities and reduced thermal stability. The findings support the strategic valorization of inorganic industrial waste in the development of cost-effective, circular TES systems for industrial heat management and energy transition. © Published under licence by IOP Publishing Ltd.
