What is GCV?
GCV is the full form of gross calorific value. The calorific value is the amount of heat generated during the combustion of a specified quantity. The Calorific value is the total energy released as heat when a substance undergoes complete combustion with oxygen under standard conditions. The higher heating value (HHV; gross energy, also known as an upper heating value, or gross calorific value GCV , or higher calorific value; HCV) indicates the upper limit of the available thermal energy produced by the complete combustion of fuel. It is measured as a unit of energy per unit mass or volume of a substance. Each fuel has a unique GCV, and the cost of fuel is largely determined by the GCV: Credits: Heat of combustion
