Jun 11, 2020The calorific value is usually expressed as the higher heating value or gross calorific value (GCV) ( Patel et al., 2007 ). Estimation of GCV from the elemental composition of fuel is one of the basic steps in performance modeling and calculations on combustion systems ( Channiwala and Parikh, 2002 ).
