The fuel potential of six tropical hardwoodspecies namely: Triplochiton scleroxylon, Ceiba pentandra, Aningeriarobusta, Terminalia superba, Celtis mildbreadii and Piptadenia africana were studied.Properties studied included species density, gross calorific value, volatilematter, ash content, organic carbon and elemental composition. Fuel propertieswere determined using standard laboratory methods. The result indicatesthat the gross calorific value GCV of the species ranged from 20.16 to 22.22MJ-kg and they slightly varied from each other. Additionally, the GCV of thebiomass materials were higher than that of other biomass materials like; wheatstraw, rice straw, maize straw and sugar cane. The ash and volatile mattercontent varied from 0.6075 to 5.0407%, and 75.23% to 83.70% respectively. Theoverall rating of the properties of the six biomass materials suggested that Piptadenia africana has the best fuelproperty to be used as briquettes and Aningeria robusta the worse. This study therefore suggests that a holisticassessment of a biomass material needs to be done before selecting it for fuelpurpose.
