Facing a significant challenge of the shortage problem of fossil fuels coupled with environmental damage has made the awareness of the development of alternative energy sources an urgent. For fulfilling rising daily energy demands, biomass-based energy is one of the most significant renewable energy sources. In this paper, we discuss about the combustion profiles (Ultimate, thermal and gasification) of the fast-growing biomass woody materials (Morinda tinctoria and Parkia biglandulosa). In the ultimate analysis, the carbon and hydrogen content (59.43 % and 10.54%) for M. tinctoria and (58.52% and 8.56%) P. biglandulosa, have major constituent of hydrocarbon which yield higher heating value. Thermal analysis of lignin decomposition for M. tinctoria is at 807oC and P. biglandulosa is at 787oC, which indicates that the two woody materials are suitable for thermochemical conversion process. The gasifier efficiency for M
