Fabrication and Household Level Evaluation of Wood Gas Cook Stove Using Control Cooking Test Method

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.
