Webconventions. The variability in results is shown in Table 1. For comparison the lower heating values calculated from default value (HHV) from B415 are also shown in Table 1. Table 1 Heating Values 1 ASTM D 5865-07a: Standard Test Method for Gross Calorific Value of Coal and Coke 2 ASTM E 711-87: Standard Test Method for Gross Calorific Value of ... Web[1] The lower heating value (also known as net calorific value) of a fuel is defined as the amount of heat released by combusting a specified quantity (initially at 25°C) and returning the temperature of the combustion products to 150°C, which assumes the latent heat of vaporization of water in the reaction products is not recovered.
