Calorific values of wood species of Nigerian origin

Abstract

Calorific values of samples of fuel wood and charcoal from nine different wood species were determined by using a bomb calorimeter. The wood species azadritcha indica and cassia siamea had the highest calorific values of 358.0 and 300.6 kJ/kg respectively, while the charcoals of poliostigma thonningii, anageissus leiocarpus and azadritcha indica had the highest calorific values of 405.7, 382.4 and 303.0 kJ/kg respectively. In general, charcoal as value added fuel has higher calorific value than the corresponding woodfuel and is recommended for domestic use because of better combustion qualities.
