Fuel Characterization of Briquettes Produced from Corncob and Rice Husk Resides.

Abstract

The selection or choice of agro-waste briquettes for domestic and industrial cottage applications depends on the fuel properties. In this work, investigations were carried out on properties of briquettes produced from corncob and rice husk residues with a view to finding out which of the two residues examined can be used more efficiently and rationally as fuel. Ultimate and proximate analyses were carried out to determine the average composition of their constituents. A simple prototype briquetting machine was fabricated to facilitate densification of these residues into briquettes. The results of this work indicate that briquettes produced from these two residues would make good biomass fuels. However, findings show that corncob briquette has more positive attributes of biomass fuel than rice husk briquette. It has a moderate moisture content of 13.47%, higher density of 650 kg/m 3
