WebThe heating value is usually measured in units of energy per unit mass of the substance, for example, kJ/kg, kcal/kg, or Btu/m 3. The three ways to express the heating values or calorific values of fuels are the lower heating value (LHV), higher heating value (HHV), and gross heating value (GHV). HHV is obtained by reversing all the products ... WebLowerHeatingValue [kJ/kg, kJ/kmol, J/kg, J/kmol, Btu/lbm Btu/lbmol] returns the specific lower heating value of the specified substance at a reference temperature of 25 C (77 F).
