摘要：The amount of energy available for consumption is a criterion for economicdevelopment of any nation. The necessity to develop alternative energy sources forfossil fuel is evident due to its scarcity, increase in price and non-renewability. Thedevelopment of energy from biomass is one area among the various energy alternativesthat has considerable promise and is receiving attention. The study investigated theeffect ultimate and combustion characteristic of homogenous and composite briquettesproduced from three agricultural residues in the ratio of 50:50. The results obtainedshows that carbon and hydrogen content of composite briquettes are higher than theircorresponding homogenous briquettes. The increased in the carbon and hydrogencontent led to increase in calorific value of composite briquettes which ranges between18.77 and 19.28 MJ/kg while for homogenous briquettes is between 17.71 and 19.09MJ/kg. A graph of calorific value against total hydrogen and carbon contents showsthat the calorific values of the briquettes is not linearly related to their total hydrogencontents but directly related to their total carbon content. The coefficient R2, whichrepresent the correlation between calorific values and total carbon and hydrogencontents were calculated as 0.9858 and 0.0365 respectively. The combustioncharacteristics also shows considerable advantage of composting agricultural waste with thermal efficiency and combustion rate of composite briquettes ranging between 25.25 and 31.69% and 1.63 and 1.71 g/min respectively while that of homogenous briquettes ranges between 19.67 and 23.67% and 0.189 to 0.225 g/min respectively. It could be concluded that production of composite briquette of agricultural waste should be encouraged.
