Estimation of Energy Potential for Solid Pyrolysis By-Products Using ...

The fuel heating value can be classified as Higher or Lower Heating Value (LHV). The High Heating Value (HHV) otherwise known as heat of combustion or Higher Calorific Value or Gross Calorific Value (GCV) or Gross Energy or Upper Heating Value is the total amount of energy released during the fuel complete combustion per fuel specific quantity.
