Abstract

In an effort to provide an affordable firewood alternative to the rural households in Nigeria, a study was carried out to compare some properties of bio briquettes (elephant grass and spear grass) and biocoal briquettes prepared at moderate pressure, 5MPa and ambient temperature with wood samples. It was found that elephant grass and spear grass have calorific values of 15.98MJ/kg and 16.13MJ/kg, densities of 0.319g/cm3 and 0.367g/cm3, durability ratings of 92.42% and 90.54% and moisture contents of 8.00% and 7.9% respectively. Comparing these properties with some wood samples, it was observed that there is a need to enhance the heating values and energy densities of the briquettes in other for them to compete favourably with firewood especially for industrial applications. Proximate analyses shows that the elephant grass and the spear grass used contained calorific values of 14.66MJ/kg and 15.12MJ/kg, moisture content of 9.26% and 10.13% and ash contents of 5.18% and 6.18% respectively.
