Abstract
Evaluation of combustion properties of biomass wood species is becoming more needful to improve and enhance the development of their utilisation as energy fuels. The study evaluates the particle size effect on energy potentials of commercially available tropical wood residues - Teak (Tectona grandis, TG), Apa (Afzelia africana, AA) and Ara (Albizia pedicellaris, AP), collected from Ilorin, Nigeria. These tropical wood species were pulverised into different particle sizes of less than 0.25 mm, 0.25 - 0.5 mm and 0.5 - 1.0 mm. The moisture content, volatile matter, ash content, fixed carbon, calorific (heating) value and elemental composition of these wood species samples for different particle sizes were evaluated in accordance to ASTM standards. The particle size of 0.5 - 1.0 mm presented the best quality within the considered particle sizes. Sample AA has the highest calorific value of 30.03 MJ/kg at particle size of 0.5 - 1.0 mm, while sample TG has lowest energy value at less than 0.25 mm with energy content of 8.84 MJ/kg. The results obtained revealed that particle size plays a significantly role in combustion properties of woody biomass residues as solid fuel.
