Abstract:

In this paper, thermal characterization of four Ugandan woody biomass species wascarried out in order to ascertain their suitability for gasification for small-scale biopowergeneration. The analyses and tests covered the aspects of proximate analysis, ultimateanalysis, heating value, Thermogravimetric Analyses (TGA), ash melting and chemicalcomposition. Eucalyptus grandis revealed ideal properties that make it the most promisingwood specie for gasification applications. Furthermore, the low ash content in E. grandissignificantly minimizes the possibilities of ash deposits on the gasifier and heat exchangersurfaces. The high fixed carbon in Terminalia glaucescens, Acacia hockii and Combretum mollemakes these species ideal for charcoal making (pyrolysis). Due to high ash meltingtemperatures demonstrated by these samples, their pyrolysis and gasification can thereforetake place with minimal worry of the ash related problems.
