The Influence of Calibration Furnace Geometry on Temperature Uniformity

The geometry of a thermocouple calibration furnace has a significant impact on the temperature uniformity within the chamber. A well - designed furnace geometry can minimize hot and cold spots, ensuring that all thermocouples placed inside are exposed to a consistent temperature. For example, in a cylindrical tube furnace, the diameter and length of the tube are carefully optimized. A larger diameter may improve the space for thermocouple placement but can also pose challenges in achieving uniform heating. Some tube furnaces use helical heating elements wound around the tube to provide more even heat distribution. In box - shaped furnaces, the shape and size of the interior chamber, as well as the location of the heating elements, are crucial. Heating elements placed along the walls and at the top and bottom of the chamber can be arranged in a pattern to create a more uniform temperature field. Computational fluid dynamics (CFD) simulations are increasingly being used to optimize furnace geometry. These simulations can predict the flow of hot air or gas within the furnace and help in designing the geometry to enhance temperature uniformity.
