Abstract: 2.7 billion People worldwide use solid biomass fuels for cooking, heating, and providing their daily energy needs. In most of the developing nations, the energy demand per household is covered mainly by woody biomasses. For instance, agricultural residues, animal dung, and charcoal are among the principal solid biomass fuels used in rural households for cooking and lighting. This research work aims to fabricate and performance evaluation of a wood gas stove for cooking purposes. The control cooking test (CCT) was conducted for wood gas stove evaluation and the results were compared with three stone traditional stoves and other related literatures. The stove’s experimental performance was evaluated by cooking with potatoes and analyzed by the control cooking test version 2.0 spreadsheet using two pots (3.5 L and 5.5 L) with and without an insulator using conifer wood. The CCT experimental results indicate that the average specific fuel consumption and time for cooking 2,282 g of potatoes were 98 g/kg, 142 g/kg, and 24 min, 28 min. for the wood gas cook stove with and without an insulator, respectively, using a 3.5 L pot. The average specific fuel consumption and cooking time for cooking 2,745 g of potatoes were 171 g/kg, 271 g/kg, and 27, 30 min. for the wood gas cook stove with and without an insulator, respectively, using a 5.5 L pot.

Abstract: Participatory popularization and demonstration of household biomass stove was conducted mainly in coffee producing districts of Jimma zone (namely, Manna, Gomma, Gera, and Shabe Sombo districts). The main studies of this research were to popularize the stove, to create wider demand on stove, to create and strengthen linkage among possible actors, to enhance multiplication and dissemination of the stove and to collect relevant feedback from the farmers. Water boiling test of the stove was carried out by using coffee husk and 3.5 L of pot at different phase. From WBT using 3.5 L of pot, thermal efficiency, specific fuel consumption, fire power and time to boil water during hot start phase were 29%, 125 g/L, 9,899 watts and 7.7 min whereas during cold start phase were 28.53%, 127 g/L, 8,868.84 watts and 8.9 min respectively. For the success of the activity, training program was organized for the farmers, development agents, and other agricultural experts. A total of 97 participants attended the training, with 85.2% being farmers and the rest were agricultural experts (development agents and subject matter specialists). To share experiences among the participants and access their feedbacks, mini-field days were conducted with 91 (58.2% female and 41.8% male) participants. Following a field demonstration, a focus group discussion with 26 farmers revealed a positive perception of the stove across all assessed attributes. This universally positive response strongly recommends further production and dissemination of the stove through coordinated stakeholder efforts.
