ABSTRACT
Biomass is one of the best and widest areas that has attracted the world's attention as regards the production of energy from renewable sources. A large proportion of world energy sources is renewable energy. Improved biomass cookstoves are recently developed devices for domestic cooking utilizing biomass as fuel through gasification. In Ethiopia, biomass is the most widely used source of energy for cooking and heating applications. This study attempted to enhance the thermal efficiency of domestic cookstoves used in Ethiopia. The developed model was tested experimentally using the water boiling testing protocol (WBT). Results showed that the stove had a thermal efficiency of 45.17%, with specific fuel consumption of 11.53 g/L and 43–48 minutes of cooking time. The mathematical model was implemented and validated, and the experimental results showed that there was an improvement of the stove, as well as reduced fuel consumption and cooking time.
