1. Introduction. Coal plays a vital part as an energy source. 1 In the mining process, it is transported to a coal bunker by belts. 2 A coal bunker is a relatively closed environment, with only two outlets at the top and bottom, and the heat is not easily diffused outward, causing the temperature of the coal body to gradually increase. Generally, the height of a coal bunker is …
