Calorific value — is the amount of heat released during the complete combustion of a certain amount of fuel boiler. This indicator is measured in joules (J) or kilocalories (kcal) per unit of mass (for example, per kilogram) or volume of fuel (for example, per cubic meter).
Calorific value: basic aspects
- Lower calorific value (LCV): Takes into account only the heat released during combustion of fuel without taking into account the latent heat of vaporization of water that is formed during combustion.
- Higher calorific value (HCL): Takes into account the total amount of heat released, including the heat released during condensation of water vapor in the combustion products.
- Dependence on fuel type: Different types of fuel (e.g. wood, coal, natural gas) have different calorific values, which is important to consider when choosing fuel for heating systems or power plants.
It is a key indicator for assessing fuel efficiency, influencing fuel selection for heating, power generation and other applications.
