The calorific value of power plant coal is the amount of potential energy in coal that can be converted into actual heating ability. Calorific value of coal can be determined either by calculation from chemical analysis or by burning a sample in calorimeter ; Calculation of CV of coal based on proximate analysis gives very rough estimate of calorific value of coal but is used for deciding the

Energy Content in Coal. 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

Why energy efficiency? Much effort is currently being focused on reducing greenhouse gas emissions from coalfired power generation. However, it is just as important to reduce the amount of carbon dioxide (CO 2) that ends up in the waste flue gas that comes out of the flue stack of a power is done by improving the efficiency of the coal combustion process.
