- Description: In this study, flue gas emissions from the combustion of eco-fuel briquettes in a ceramic lined stove were investigated. The eco-fuel briquettes were made of biomass and other waste material such as spent coffee beans, mealie husks, saw dust and coal fines using a hand operated screw press. A combustion set-up consisting of digital weightometer, ceramic lined stove and a complete chimney system was used. The emissions from the combustion process were measured using a Testo 350 gas analyzer linked to the chimney system. The eco-briquettes made from a mixture of waste biomass burnt cleanly within the acceptable exposure limits as set out by Occupational Safety and Health Agency (OSHA). The measured gross calorific value was 18.9MJ/kg with a burning rate of 2g/min. These properties make eco-fuel briquettes suitable for domestic applications.

- Description: In this study, the theoretical relationship between pressure and density was investigated on cylindrical hollow fuel briquettes produced of a mixture of fibrous biomass material using a screw press without any chemical binder. The fuel briquettes were made of biomass and other waste material such as spent coffee beans, mielie husks, saw dust and coal fines under pressures of 0.878-2.2 Mega Pascals (MPa). The material was densified into briquettes of outer diameter of 100mm, inner diameter of 35mm and 50mm long. It was observed that manual screw compression action produces briquettes of relatively low density as compared to the ones made using hydraulic compression action. The pressure and density relationship was obtained in the form of power law and compare well with other cylindrical solid briquettes made using hydraulic compression action. The produced briquettes have a dry density of 989 kg/m3 and contain 26.30% fixed carbon, 39.34% volatile matter, 10.9% moisture and 10.46% ash as per dry proximate analysis. The bomb calorimeter tests have shown the briquettes yielding a gross calorific value of 18.9MJ/kg.
