The heating value, also known as the calorific value or energy value, is the amount of heat released during the combustion of a fuel. It is measured in units of energy per unit of the substance, such as kJ/kg. The higher heating value takes into account the latent heat of vaporization of water in the combustion products, while the lower heating value does not. Heating values are commonly determined through the use of a bomb calorimeter.

- 2. Heating value The heating value (or energy value or calorific value) of a substance, is the amount of heat released during the combustion of a specified amount of fuel. It is measured in units of energy per unit of the substance, kJ/kg, Heating value is commonly determined by use of a bomb calorimeter.
- 3. heat of combustion The heat of combustion is the energy released as heat when a compound undergoes complete combustion with oxygen under standard conditions.
- 4. Heating values • The higher heating value (HHV), (also known as the gross calorific value or gross energy) of a fuel is defined as the amount of heat released by a specified quantity (initially at 25 °C) of fuel, it is combusted and the products have returned to a temperature of 25 °C. • The higher heating value takes into account the latent heat of vaporization of water in the combustion products, • Or Lower calorific value (LCV)) is determined by subtracting the heat of vaporization of the water vapor from the higher heating value.
