Calorific Values

Calorific Value

The calorific or heating value is an important indicator of the quality of pressed fuel briquettes . It measures the energy content of the briquettes. It is defined as the amount of heat evolved when a pressed fuel briquette is completely burnt and the combustion products are cooled. The Gross Caloric Value, shortened as GCV, refers to the calorific value with the condensation of water in the latent heat also known as higher heating value.
