Abstract

The gross calorific value (GCV) of a fuel, also known as the higher heating value (HHV) or gross heat of combustion, is the amount of heat released by a specified quantity (initially at 25°C) once it is com-busted and the products returned to that temperature. Fuwape (1989) noted that extractive-free wood from Gmelina arborea (Roxb), a hardwood, had a lower gross heat of combustion than the unextracted wood. In a later study, finding that extractive-free plant parts resulted in lower HHVs than the unextracted parts, Demirbas (2003) produced an equation relating the differential HHV to extractives content.
