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 about 3050 m ...

The mill outlet temperature of coalair mixture is maintained between 65 to 90 degree centigrade in the case of low and medium volatile coal. In the case of high volatile coal, while the lower limit generally remains as 65 degree centigrade, the upper limit is restricted to a lower level depending on percentage of volatile content in coal.
