Development of a waste heat recovery power generation system

Abstract

In this study we use thermoelectric effect technology to design and build a thermoelectric power generation system to recover the heat generated by combustion gases to generate electricity. This system consists of heat collection system, cooling system and power generation system. In this paper, the prototyped of a medium-temperature waste heat recovery power generation system was designed, fabricated, and tested. A total of 60 thermoelectric chips are installed in the power generation system. Based on the experimental results, the output current and voltage are 1.05A and 56.4V at the temperature difference between the two ends of the thermoelectric chip is 109.4 °C, and the output power is approximately 60W. Furthermore, each part of the device can operate independently, which is very suitable for the industry.
