Coal mined at Amax's Belle Ayr mine averages only % to % sulfur. The result is a clean burning fuel. But the coal's moisture content averages about 30% and its heating value rates about 8860 kJ (8400 Btu). Amax decided to do something about the moisture in its Wyoming coal. Dry the coal, remove some of the moisture, and raise the heating ...

The main parts of a coal drying plant typically include:. 1. Feed chute: This is the inlet through which the wet coal enters the rotary dryer. 2. Rotary drum: A cylindrical drum rotates slowly, allowing the coal to be heated and dried evenly. 3. Burner: It provides a heat source for drying the coal. It can be fueled by natural gas, coal gas, diesel, or other fuels.

Coal drying. Coal preparation plants that employ fine coal cleaning by froth flotation can produce an unacceptable amount of moisture in the product. Thermal drying, in which the wet coal is dried in the hot gas generated by a coalor gasfired burner, is used in some plants to reduce the moisture content. Refuse and tailings management.
