OPEN ACCESS Freely available online Experimental Investigation of Biogas Injera Baking Stove Using Circular Ring Pipe Burner Taha Abdella Geda * , Demis Alemu Ambie, Kamil Dino Adem Department of Mechanical and Industrial Engineering, Addis Ababa Institute of Technology, Addis Ababa, Ethiopia ABSTRACT Baking and cooking are day-to-day human activities that demand energy from different sources. Injera is stapled food in Ethiopia mainly baked by traditional biomass injera baking stove. In order to minimize the environmental and social impact of traditional non-clean energy sources of energy, different research has studied replacing traditional stoves with clean and renewable energy sources. However, still the existing injera baking stove has low performance and heat distribution problems. The purpose of this study is to solve this problem by developing injera baking biogas stove with better performance. The experimental investigation was conducted using a biogas plant in Addis Ababa University 4 Kilo Campus. A detailed energy analysis of energy demand, energy output, and baking performance has been performed. Injera baking time is 3 minutes, idle time is 2 minutes between successive injera baking. Thus, the designed injera baking biogas stove achieved uniform heat distribution and improved performance. Keywords: Biogas injera baking stove; Burner; Performance INTRODUCTION Biogas can contribute to reduce the reliance on solid biomass energy sources, improving environmental sustainability, as well as the welfare of rural households. Biogas has the dual advantages of providing energy for rural households such as energy for lighting and for cooking, while at the same time providing high-quality organic fertilizer from the slurry produced after the gas is extracted. Biogas improves the quality of life of rural households as it reduces indoor air pollution and is non-polluting hence no harmful gases such as CO 2 , CO, NO 2 , and SO 2 are evolved. Enhance the share of renewable energy, minimizing dependency on fossil fuels. The method of disposal is safe and efficient and hence no space is wasted in the form of landfills. Biogas cooking stove is widely used in developing countries; however, it is not yet popular for injera baking. There are a number of efforts by the Ministry of Water, irrigation and electricity-Alternative Energy Development Directorate and SNV to develop a bio-gas stove for baking injera. In 1996, a biogas injera baking stove was tested. It was a three-ring stove consisting of three concentric rings made from a ½’’ steel pipe. The performance of the concentric three-ring injera stove was determined by baking injera. The power output of the stove was 11 kW, corresponding to the gas consumption 41 l/min. The gas consumption per injera was 193 l (3108 kJ/injera). The average efficiency of the three-ring biogas stove was 16% in the range of improved biomass stove. This result indicates that performance of stove is quite low for a biogas gas stove [1]. Dejene Kebede et al., at the Institute of Technology of Bahirdar University attempt to design biogas stove used for Injera baking. The stove was designed by covering the flame under an insulated material. Burner for the biogas was designed based on the demand for energy needed during baking and the amount of gas supplied from the biogas plant. Heat transfer analysis between burner and mitad by radiation, convection heat transfer between flame and wall and heat flow through insulation also was assessed on the paper to come up with a suitable injera baking biogas burner. Getu Alemayehu partnering with SNV has successfully demonstrated application of the biogas stove for injera baking application. The newly tested stove demonstrates the lacks uniformity of heat in the Mitad to bake Quality injera. Although efforts have been done to develop injera baking stove, still there is problems with low stove efficiency and low heat distribution throughout baking pan. Hence biogas injera baking stove is to be developed which meet the requirement of heat distribution and efficient performance. The new stove has a conical shape burner with a lower diameter of 150 mm and an upper diameter of 500 mm. Clay Injera baking pan of 450 mm and 15 mm with thermal conductivity of 5 W/m .K and specific heat capacity 0.83 KJ/kg.K is used in this experiment. The motivation and objective of this project is to 26 -Feb-2024, Manuscript No. JFPT-23-23893 (R);
