Calorific value COALspotHow to Calculate a Calorific Value Sciencing

CALORIFIC VALUE The heating value or calorific value of a substance usually a fuel or food is the amount of heat released during the combustion of a specified amount of it The calorific value is a characteristic for each substance It is measured in units of energy per unit of the substance usually mass such as kcal/kg kJ/kg J/mol Btu/m³Mar 13 32 Calorific value is the amount of heat produced by the combustion of a fuel mass and is typically expressed in joules per kilogram All elements considered to be fuels have a calorific value There are two calorific values for fuels higher and lower Higher assumes that water vapor is totally condensed and the heat
