Abstract
This project presents a set up of a thermoelectric power system that uses liquid fuel, fired through a porous media burner. The aim of the study is to evaluate the capability of the thermoelectric module to generate electricity based on the heat produce by the combustion of the liquid fuel. The system uses kerosene as a fuel, combust with variety of equivalence ratio between Ø = 0.813 to Ø = 18.227. Heat as the product of the combustion is measured using a thermal imager device, and the power generated by the thermoelectric module is measured using multimeter and it is found out that at an equivalence ratio equal to one, the module generate the highest power, where P = 1.056 W with average temperature of T = 437.25 °C. The power generated at fuel-lean region with Ø = 0.813 is P = 0.602 W with average temperature T = 425.04 °C. Whereas the power generated at fuel-rich region with Ø = 2.036 is P = 0.293 W with average temperature of T = 500.62 °C. It is found out that the highest power generated can be obtained at Ø = 1, and the power generated decrease with lower or higher value of Ø. However, the measured temperature is found out to increase with increasing period of combustion. Hence, the performance of the thermoelectric power generating system is evaluated and achieve at both fuel-lean and fuel-rich region.
