Abstract

Sawdust and rice husk are available in abundance and indigenous in
Nigeria but have not been exploited because they cannot be used
directly in combustion processes due to their loose form unless by
pelleting or briquetting. This experimental study assesses the
potential of pellets from sawdust (SD) and rice husk (RH). Pallet
samples collected from mills were thereafter optimized in ratios (i.e.
90%RH:10%SD, 80%RH:20%SD, 70RH:30SD, 60%RH:40%SD,
50%RH:50%SD, 100%RH and 100%SD) using mixing ratio
optimization model. Seven samples were produced using a manual
screw press machine and were subsequently categorized in terms of
calorific value (CV), proximate and ultimate analyses using the ASTM
standards. Results showed that the 100%RH pellets have higher CV
of 31,026.3kJ/kg and the 100%SD a value of 26,088.3kJ/kg while the
optimized pellets range from 25,867.39kJ/kg to 27,063.60kJ/kg. The
CV decreases with increasing ash content of the pellets. It was also
observed from the proximate analysis that the 100%RH has low
percentages of moisture content, volatile matter and ash content
compared to others. The optimized pellets showed that SD has the
tendency to reduce the sulfur content in RH; hence, a promising
alternative source of energy to the conventional fossil fuel.
