Evaluating the Efficiency and Functionality of a Stirling Engine-Based Multiple Fueled Biomass Stove

Marvin C. Credo, Danilo P. Metra Jr.


Manual fanning is the usual method used to provide air necessary for burning the fuel in a charcoal or wood fueled stove. However, several innovations use a blower fan to provide the said air. This study aims to design and develop a multiple-fueled biomass stove with a blower fan that operates on a renewable energy source provided by a Stirling engine. Evaluation of the developed prototype in terms of efficiency and functionality was conducted. The stove was found to be functional and efficient, with only minimal differences between the voltage and current outputs when supplied by the conventional AC outlet,compared to when supplied by the Stirling engine. However, t-test results show that there exists a statistically significant difference between the two datasets about the speed rotation of the blower fan(rpm), which indicates that using conventional AC outlet as the supply results in higher speed rotation of the blower fan compared to using the Stirling engine. These results also revealed that having a minimal difference between the current and voltage outputs can have a significant effect on the speed rotation of the said blower fan, thereby affecting the performance of the developed prototype’s efficiency. Thus,if other researchers attempt to modify the stove design, it is recommended to use a Stirling engine with more power capacity to maximize the speed rotation of the blower fan.
