“…Numerical validation with the literature [22] gives agreement with a maximum car of 6%. This result is better compared to Bagaya's study [16] on the biogas stove, for which η = 55%, therefore acceptable according to the literature [25]. However, the energy performance of the home will drop in a busy kitchen, but its adoption by a cooking stove is already an important step in reducing wood cutting in Burkina Faso.…”

This study seeks to propose a new model of hearth for the consumption of biogas produced by a biodigester of 4 m-3. The cylindrical furnace is used to heat an empty pot for 3 hours. To do this, the system is subdivided into two sub-systems, the first is the flame, which heats the bottom of the pot. The latter is the second hottest point. The developed network is composed of 8 isothermal points, interconnected by thermal resistances, each of which represents a particular type of heat transfer mode. The resolution of the system required 8 differential equations. The modeling allowed us to appreciate the temperatures governing the system. The experimental study proves an agreement with the model temperatures. Studies show that the cook stvoe’s optimal thickness and height are respectively 18 mm and 09 cm. The heat ide the internal air of the kettle is 2200C and the flame temperature is 9000C. The instantaneous efficiency of the cook stove obtained is 65%. In addition, a validation with literature data to confirm this study with maximmum gap of 5%, therefore its adoption will lead to reducing the consumption of biogas and therefore have a positive impact on the woodcut.

“…This is because the thermal gradient transferred to the pot at this height (10cm) and thickness (14mm) remains high. The cook stove's efficiency of 65% is already an advance (Bagaya et al, 2021) with an empty pot whose air is not controlled. So, we're saying that cooking a dish under the same conditions will produce faster results.…”

According to Burkina Faso's fifth general population and housing census, published in 2022, the total population is 20,505,155, with 3,488,258 households (Bagaya et al, 2021). According to this census, 83.5% of households use firewood and coal in rural areas, and only 16.1% of Burkina Faso's population uses gas or biogas.…”

The cook stove is usually constructed from black-painted sheet metal, to better absorb energy. To enhance thermal performance, a theoretical cylindrical design is proposed in this article. This article aims to study this design and compare its performance with the conical design. Theoretical modeling of the cook stove was carried out considering heat transfer by radiation, convection, and conduction based on a steady-state thermal network, and solved using the Matlab R2021b® platform under license (License No. 595687). The result of the theoretical analysis predicts a theoretical efficiency of 65%, a pot air temperature Tf=220oC and a flame temperature Ta=900oC. Similarly, a validation with Sagouong's model on combustion chamber temperature and Kaushik's model on thermal efficiency. A maximum threshold (RMSE) of 4% is observed between the two studies. The Tc temperature stagnates rapidly within 5 minutes at 600oC and the comparison showed that the firing temperatures of the cylindrical shape are higher than those of the conical-shaped cook stove. Consequently, the performance of the cylindrical-shaped cooking stove can be improved by further experimentation and flue gas analysis.

The present work on the production of biogas from cow dung substrates was carried out at the Laboratory of Renewable Thermal Energy (L.E.T.RE) of the Joseph KI-ZERBO University in collaboration with the National Program of Biodigester of Burkina Faso (PNB-BF). We focus in this work on the determination of the physicochemical characteristics of the substrates allowing the follow-up of the biogas production. We experimented with anaerobic digestion for 100 days each at mesophilic temperature, i.e. a hermetic enclosure included between 27 and 38\(^{\circ}\)C. The average flow of biogas is Q = 2.5 m3 d -1, and that of methane is 1.9 m3 d -1. This methane-rich gas CH4 with a flow rate of 1.9 m3 d -1, i.e. a rate of 60% in the biogas, has a high energy capacity of 23kJm-3 and can be used for cooking and lighting especially in rural areas. The following physicochemical characteristics were observed for cow dung: dry matter 11.85%, volatile matter 58.83%, hydrogen potential 7.01, density 731 kg.m-3, carbon content 33.32%, nitrogen content 1.46%, nitrogen-carbon ratio 24.70, acids are around 0.18 kgCODm-3, and the average chemical oxygen demand 30 kgCODm-3. This characterization was performed on a 4m3 pilot bioreactor with daily substrates loading ranging from 20 to 30 kg. The temperature of the reaction medium remained around 35\(^{\circ}\) C, optimal for the mesophilic operation of the bioreactor. The results obtained making it possible to demonstrate the possibility of producing a large quantity of flammable biogas in a continuous manner are in agreement with the literature on methanization.
