Eco-Friendly Industrial Biofuel Oven From Locally Sourced Renewable Agricultural Waste Chidume Nwambu Chilee Ekwedigwe Victor Nwoke Ngozi OkelekweCharles Nwankwo<p>The study design and develop a highly energy-efficient biomass stove using waste biomass as fuel and recovering waste heat from the combustion chamber for the drying function. The system uses a single thermal energy source to power both the drying and product chambers. Four industrial thermometers were placed in each of the three chambers and one outside to simultaneously record their instantaneous temperature values. Temperature data were taken every 20 seconds for the duration of the 900-second experiment. Only the three thermometers in the chambers started to react appropriately as soon as the combustion began. The combustion chamber recorded 520⁰C, the product chamber recorded 98⁰C, and the drying chamber recorded 170⁰C after 900 seconds. Calculations reveal that during the same period, the combustion chamber produced 891.00J/s of heat energy, while the drying and product chambers absorbed 217.50J/s and 569.70J/s, respectively. Consequently, the product and drying chambers’ thermal efficiencies are reported as 63.94% and 24.41%, respectively, bringing the system’s overall thermal efficiency to 88.35% with the system ultimately losing 11.63% of the total thermal energy generated. The composite insulation enhanced the thermal insulation of the system, thereby contributing to its improved conservation of energy. Therefore, to achieve optimal thermal energy consumption and improved thermal efficiency in the heating of food items, this biomass stove will be crucial. Waste biomass is a good source of thermal energy that can be used in place of other energy sources, particularly fossil fuels, and end the devastating effects of the energy challenge in the agro-processing industry.</p> Journal of Civil Engineering and Environmental Sciences - Peertechz Publications 2026-06-30 Research Article https://doi.org/10.17352/jcees.000099 en Copyright © Chidume Nwambu et al.
