Experimental Study of the Effect of Pressure and Temperature on the Performance Efficiency of aMini Biomass Stove

Access to efficient and clean cooking energy is a critical concern, particularly in rural regions where biomass burning is still widespread. This research conducts empirical tests with the aim of ascertaining the impacts of air pressure and initial fuel temperature on the thermal efficiency of the mini biomass cooker. A standard Water Boiling Test (WBT v4.2.3) was performed under different air pressures (10, 20, and 30 Pa) and different fuel temperatures (27°C, 40°C, and 60°C) to simulate different performance conditions. From the results, it was seen that as both air pressure and initial fuel temperature increased, the thermal efficiency greatly improved. The maximum thermal efficiency of 89.37% was obtained at 30 Pa and 60°C, which was also the lowest fuel consumption of 18.49 grams and the shortest boiling time of 8.11 minutes. The rise in flame temperature was solely due to a decrease in boiling time and improved heat transfer. These results validate that maximizing operational conditions like airflow and fuel preheating has the potential to enhance combustion efficiency significantly without any alteration in the design of the stove. This study offers beneficial knowledge for the design and optimization of biomass cooking stoves, making it easier to develop more efficient, cleaner, and more sustainable household energy sources
