Modeling and Validation of Biogas Consumption Prediction in Cook Stove Using a Network Approach
Asian Journal of Physical and Chemical Sciences, Volume 10, Issue 4,
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.
