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

15/10/2009· 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 from 10500 kJ/kg to 25000 kJ/kg depending on the quality and type of the coal.

(iii) Energy tariff (as per formula mandated by CERC) is inversely proportional to GCV. A lower GCV would thus lead to higher tariff. TMB method, which gives the lowest GCV, is used by stations for billing which would lead to higher burden on consumers. At the same time, coal companies are reimbursed on ADB (for imports) and EB (for domestic supplies) which gives a higher GCV and hence higher ...
