Q2. Coal gcv of power plant
Ans. 
Coal Gross Calorific Value (GCV) is a key parameter in determining the efficiency of a power plant.
• GCV is a measure of the amount of heat released when a unit mass of coal is combusted.

• It is typically expressed in units of kilojoules per kilogram (kJ/kg) or British thermal units per pound (Btu/lb).

• Higher GCV coal is preferred in power plants as it produces more energy per unit mass.

• The GCV of coal can vary depending on
