Structural advantages of Oven

We compared three common ovens (octagonal, sector and cylindrical) ,that is, the volume of the oven with different structures was compared with the endothermic area of the hot cavity when the diameter of the ovens were the same. The results showed that compared with octagonal oven and sector oven, the spatial utilization ratio of cylindrical oven was increased by 10%~ 20%, which was more energy-saving and efficient.
