Experimental Investigation of Biogas Injera Baking Stove Using Circular Ring Pipe Burner

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 stoves. 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, the developed 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. Baking time is 3 minutes, Idle time is 2 minutes and efficiency is 68%. Thus, this injera baking biogas stove has achieved uniform heat distribution and improved efficiency and hence can be used for injera biogas injera baking stove.
