Abstract
This study aims to analyze the heat transfer characteristics in a Saoma Inox 5005 model, modified for the use of aluminas in its oven. According to studies related to porous burners, the use of the ceramic porous media consisting of spheres of alumina, results in a better use of the energy of irradiation of the furnace. This is due to the properties of the alumina that allow a better utilization of the irradiated thermal energy. In the test a thermal camera was used to record the heat transfer. The duration of the test with this setup was 20 minutes with the flame on and proximally 40 minutes cooling it down. It was noted that after cutting off the fuel supply to the furnace, the aluminas stored the heat supplied by the combustion for a longer time than the flat plate, therefore, proving to be a better thermal solution.
