Performance of Thermoelectric (TEG) for DC Electricity Power Source using Application of Stoves Rocket Heats with Resistance Variations

Rocket Stove is a wood-fired stove that functions to improve the combustion process efficiently and produce high heat. Thermoelectric generators are electrical generator devices that convert heat energy or temperature differences into electrical energy using a phenomenon called the Seebeck effect. The Seebeck effect is a phenomenon that occurs when connecting copper and iron in a circuit. Between the two metals then the compass needle is placed. When the metal side is heated, the compass needle turns to move. This happens because the electricity that occurs in the metal creates a magnetic field. This magnetic field moves the compass needle. This study aims to determine the power produced by thermoelectric generators with resistor loads. The thermoelectric generator used in this study was TEG SP1848 with 10 thermoelectric quantities. And the power test is performed with the variable resistor 1 kΩ - 10 kΩ. Parameters measured are electric voltage, electric current, and temperature. The results obtained in this study are the SP1848 type thermoelectric generator produces the largest electricity voltage at temperature difference is 34.1ºC with an electric voltage of 12.56 volts and produces the largest electric current at temperature difference is 30ºC with an electric current of 0.087 A. the temperature difference of 30ºC with electric power of 1.09794 watts. It can be concluded that the thermoelectric characteristics of the SP1848 type generator when the temperature difference between the heat side of the TEG and the cold side of the TEG increases the electrical voltage, and the electric current will be even greater
