As an important magnesia material, the energy consumption of light-calcined magnesia during its calcination process directly affects the sustainable development of the industry. This paper addresses the high energy consumption and low efficiency of traditional vertical shaft furnaces, taking an energy-saving light-calcined magnesia vertical shaft furnace as the research object. A three-dimensional geometric model was established using SolidWorks software, and finite element numerical simulation of the internal temperature field of the furnace was performed using ANSYS software. The simulation yielded temperature gradient curves and temperature distribution data of the material zone and gas passage, revealing the temperature variation law along the height direction inside the furnace. The study shows that the temperature inside the furnace exhibits a multi-segment gradient distribution, with obvious temperature zoning characteristics in the preheating, calcination, and cooling sections. The gas passage structure design has a significant impact on airflow distribution and heat transfer. The simulation results were compared with actual experimental data, showing good agreement and proving the rationality and reliability of the finite element method in studying the temperature field of vertical shaft furnaces. This study provides a theoretical basis for the structural optimization and process parameter adjustment of energy-saving light-calcined magnesia vertical shaft furnaces, and has guiding significance for reducing energy consumption and improving product quality.
