Development of Power Generation from Waste Heat in Industries using Thermoelectric Generator

The rapid growth of industries and transportation has increased energy demand and also produced a large amount of waste heat that is usually released into the environment. This unused heat represents a significant loss of energy and contributes to environmental pollution. The present study focuses on the development of a power generation system from industrial waste heat using a Thermoelectric Generator (TEG). A thermoelectric generator is a solid-state device that converts heat energy directly into electrical energy based on the Seebeck effect, where a temperature difference across two dissimilar materials generates a voltage. In the proposed system, waste heat produced by industrial machinery or exhaust gases acts as the hot side of the TEG module, while a heat sink maintains a cooler temperature on the opposite side. The temperature difference between these two sides generates electrical power. The produced electricity is measured using sensors and can be stored in a battery for further use. A microcontroller with an LCD display is used to monitor voltage and temperature levels in the system. The generated power can be used for small loads such as fans, lighting, and monitoring devices. The system provides a clean, reliable, and environmentally friendly method for utilizing waste heat and improving overall energy efficiency in industrial applications. Top of Form
