The Gross Calorific Value (GCV), also known as the heating value, is a crucial indicator of the quality of pressed fuel pellets. It measures the energy content released when the pellets are completely burned and the combustion products are cooled. This value reflects the total heat produced, including the latent heat from water vapor condensation, making it synonymous with the higher heating value. Understanding GCV is essential for evaluating fuel efficiency and optimizing combustion processes in biomass applications, ensuring maximum energy output from your pellets.
