Zusammenfassung
This work investigates the integration of a solar furnace (SF) into the smelting processes of copper in a flash furnace under Chilean solar irradiation conditions. A computer model of a 1 MWth solar furnace, inspired by the French solar furnace in Odeillo, with a total heliostat specular area of 2,835 m² was developed and the annual energy contribution of the SF for copper smelting in a flash furnace was simulated. Economic benefits through fossil fuel savings in three different flash furnaces were compared with the investment costs for a SF for a lifetime of 50 years. Furthermore, reductions in greenhouse gas emissions (CO2-eq-emissions) through fuel saving were calculated. The results show that, depending on the fuel type used in the flash furnace, up to 24% in CO2-eq-emissions and up to 10% of lifetime costs can be saved.
