Design Improvement and Performance Evaluation of an Improved Aluminum Biogas Burner for Injera Baking

Abstract

A biogas operating burner is a device used to generate a flame to heat up the product. Biogas burners have received very little attention up to this point. The effective use of the energy produced will depend not only on the energy source but also on the final technology employed to heat the product. An improved aluminum biogas burner geometry is necessary for efficient utilization of the gas coming from the biogas digester. Two problems uneven heat distribution and longer heating times associated with burner geometry pushed me to prepare such a design. The goal of this study is to improve the heat distribution throughout the baking pan and thermal efficiency of biogas burners. As a result, the baking pan will receive an even heat distribution with low emissions. The controlled cooking testing method was used to conduct the experiment. In this research work, design and performance evaluation an improved aluminum biogas injera baking burner was carried out. The performance of the newly designed biogas injera baking stove was evaluated by taking into account several key criteria during the experimental test cooking period, including temperature distribution, thermal efficiency, cooking time, and biogas consumption. As per the experimental test results, the newly developed biogas injera baking stove consumed 1.7 litters and took 1.57 minute to bake a single injera which is less compared with the previously developed biogas fuled burner which consume 2.5 litter and took 1.7 minute to bake a single injera. The newly developed injera baking burner using biogas had a thermal efficiency of 52.5 %. In comparison to the old stove, which had thermal efficiency 51 % of 8mbar operating pressure the newly developed biogas injera baking stove demonstrated a notable reduction in terms of thermal efficiency, the amount of biogas consumed, and the amount of time required for cooking.
