Energy Saving Equipment for Cooking Stove with Thermoelectric Generator

Abstract

This research aims to study, build and test the innovative prototype of energy saving equipment for stove with thermoelectric generator. The experiment will be divided into two case studies. Case A is testing the efficiency of stove without the energy saving equipment and Case B is testing the efficiency of stove with the equipment. Each case is designed to work in different environments, such as in a closed area and in the areas with difference wind speed. Experimental results show the energy saving equipment improve the thermal efficiency of cooking stove in the household as well. It was found that the thermal efficiency after installing the energy saving equipment in case B1 to B4 increased 4.68 %, 7.82 %, 12.21% and 18.58% respectively, with an average increase is around 10.82 % and saves energy up to 38.46 % in case B4 and less to 8.06% in the case B1 which operated in closed area and the average saving is around 21.7 %. The equipment generateก electricity as linear voltage around 2.5-3.0 Volts depending on the difference of temperature between hot and cold metal fin which installed at the opposite side of thermoelectric and can be used as a source of power for small electronic devices as well.
