How to Calculate the Coal Quantity Used in a Power Plant ...

The basic function of the power plant is to convert energy in coal to electricity. Therefore, the first thing we should know is how much energy there is in coal. Energy content of coal is given in terms of KiloJoules (kJ) per Kilogram (kg) of coal as the Gross calorific value (GCV) or the Higher Heating value (HHV) of coal. This value can vary ...

Coal-Fired Thermal Power Plant - an overview ...

Firstly, this is a combined cycle power plant that effectively utilizes the blast furnace gas instead of the coal fired thermal power plants popular in China. It is estimated that the plant emits approximately 1,900,000 tons less CO 2 a year (assumed operation of 7000 hours per year) than that emitted by burning coal in a coal-fired thermal power plant of the same output.
