Fabrication and Analysis of Power Generation from Waste Heat in Industries Using Thermoelectric Generator

The increasingly worldwide problem regarding rapid economic development and a relative shortage of energy, the internal combustion engine exhaust waste heat and environmental pollution has been emphasized more heavily recently. Out of the total heat supplied to the engine in the form of fuel, approximately 30 to 40% is converted into useful mechanical work. The remaining heat is expelled to the environment through exhaust gases and engine cooling systems, resulting in an entropy rise and serious environmental pollution, so it is required to utilize waste heat into useful work. As waste heat recovery techniques, such as a thermoelectric generator (TEG), are developed, they have become a promising alternative green technology due to distinct benefits of thermoelectric generators.
