| A study was undertaken to determine some energy properties of three non-timber forest tree residues: Bush Mango (Irvingia), Achi (Brachystegia eurycoma) and Para Rubber (Hevea brasiliensis) shells for fuel. The ultimate properties (Carbon, Hydrogen, Oxygen, Sulphur and Nitrogen contents) of the ground shells were determined. The proximate properties determined were volatile matter, ash and fixed Carbon contents, and calorific values. The shells for the three samples were reduced with a hammer mill to 1.00 mm, 2.00 mm and 4.75 mm particle sizes. The mean of the energy properties of the samples were compared using the New Duncan’s Multiple Range Test to determine if there were significant differences at (P ≤ 0.05). Results obtained showed that Irvingia... |
