Coal refers to natural coal mined from coal mines without any treatment. Coal is an important energy material and an important raw material for the production of chemical products. In the high-quality utilization of coal, in addition to washing and removing impurities from the coal, it also needs to be dried. So why does coal need to be dried?
1. Improve economy
Coal that has just been mined or washed contains a certain amount of moisture, cannot be burned directly, and has low calorific value. Drying the coal can reduce the moisture content of the coal, increase the calorific value, and increase the economic value of the coal.
2. Stabilize coal moisture index
Because the source of coal is uncertain, the moisture index of coal is unstable. After drying, the moisture index of coal is stable and controllable.
3. Reduce coal transportation costs
Coal that has just been mined or washed has a high moisture content and can be dried to reduce transportation costs.
