This project is aimed at fabricating an oven for a specialized drying application using infrared heating principle. The project involves construction of a miniature oven using long wave infrared heaters. The application is typically aimed at drying the coating on a sand mold used in foundries or for moisture removal of a refractory material / block. The oven has a steel fabricated casing lined with insulation materials, with inner layer fitted with high emissivity reflectors. Long wave (far) infrared heaters are mounted on two inner side walls, power supply to which is controlled by PID temperature controller which gets the signal from thermo couple. As the infrared energy heaters only the objects it strikes and not the air in its path, it is highly energy efficient. Energy Saved is Energy generated and infrared heating system stands out as an “Energy Saving Technology” compared to the conventional heating systems.
