Abstract
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.
