Calorific values and chemical composition of fast growing timber species

Different timber species generally have different chemical composition and calorific values. In solid biofuel production, logs will be debarked. The bark may affect the calorific value because of its variable chemical composition. In this study, 2 to 5 yr-old fast growing timber species (Acacia spp....

In this study, 2 to 5 yr-old fast growing timber species (Acacia spp., Endospermum spp., Macaranga spp., and Albizia falcataria) were harvested to determine the variation between chemical composition and calorific values.
