Design, modeling, and fabrication of thermoelectric generator for waste heat recovery in local process industry

Abstract

The waste heat from energy company consumption sectors, when rejected into atmosphere, are useless and it contributes to global warming. Nowadays industrial activities and energy sectors (power stations, oil refineries, coke ovens, etc.) are the most energy consuming sectors worldwide and, consequently, the responsible for the release of large quantities of industrial waste heat to the environment by means of hot exhaust gases, cooling media and heat lost from hot equipment surfaces and heated products. Recovering and reusing these waste heats would provide an attractive opportunity for a low-carbon and less costly energy resource. Moreover, reducing the environmental impact. Thermoelectric generator is the one of the method which helps to recover this waste heat, designing of thermoelectric generator was based on the range of temperature produced in industries and the objective is to generate optimum power with optimum material, Comsol Multiphysics software is the tool, which has been used to get the simulation results. High manganese silicide(HMS) has been chosen according to the properties of waste heat from industries, the simulation results shows that thermoelectric generator can be a good way to recover waste heat from local industries and converted to useful power, for instance to supply small sensing electronic equipment in the plant.
