10 yuan per ton. According to the official website of the National Energy Administration, rail freight increased by 1.5 cents per ton-kilometer. Taking Datong to Qinhuangdao Port as an example, the transportation cost of thermal coal is 10 yuan per ton. Thermal coal is coal used to produce electricity.

The water in the boiler absorbs heat and turns into steam with a certain parameter to rotate the steam turbine. The steam turbine drives the generator to produce electricity. . It is used to produce electricity, which is why it is called thermal coal.
