| Abstract Scope |
The PRéMA project aims to advance novel energy systems in the drying and preheating of furnace materials. The PRéMA project is funded by the European Union’s Horizon 2020 Research and Innovation Programme under Grant Agreement No 820561. The use of a shaft kiln to preheat manganese ore to 600 °C with hot air before smelting is proposed to introduce solar thermal energy into the production of ferromanganese alloys. A two dimensional axial dispersion plug flow heat and mass transfer model is developed to inform the control of the shaft kiln by predicting the particle temperature profile. The calculated particle temperature profile will inform the required residence time under different air flow rates to obtain the product discharge temperature. The model will be validated with experiments in a packed bed experimental rig and further compared with published heat and mass transfer models. |
