“…This new technology includes the development of thermoelectric materials and applied systems, for instance, the wall of conventional furnaces, cooling of heat pipes, devices based on structured deposed, turbo compounding, Rankine and Brayton electric utilities, thermochemical recuperation, in-cylinder waste heat recovery, and improvement of cogeneration systems; which are all used for energy harvest using solid state thermoelectric devices [4][5][6][7][8][9][10][11][12][13][14][15]. The use of thermoelectric generation brings certain advantages, such as high durability, high precision, and reduced size, besides being an excellent way of collecting residual thermal energy, which means it is a clean energy cogeneration [16][17][18][19][20].…”

Characterization of a Thermoelectric Generator (TEG) System for Waste Heat Recovery

This paper presents the development and characterization of a thermoelectric generator (TEG) system for waste heat recovery to low temperature in industrial processes. The relevance of this mode of electric energy harvest is that it is clean energy and it depends only on the capture of losses. These residual energies from industrial processes are, in principle, released into the environment without being exploited. With the proposed device, the waste energy will not be released into the environment and will be used for electrical generation, which is useful for heat production. The characterization of TEGs that are used a data-acquisition system have measured data for the voltage, current, and temperature, in real-time, for temperatures down to 200 • C without signal degradation. As a result, the measured data has revealed an open circuit voltage of V OC = 0.4306 × ∆T, internal resistance of R 0 = 9.41 Ω, with tolerance ∆R int = ±0.77 Ω, where R int = 9.41 ± 0.77 Ω. The measurements were made on the condition that the maximum output was obtained at a temperature gradient of ∆T = 80 • C, resulting in a maximum power gain of P out ≈ 29 W.

“…1 A TEG module can be regarded as a thermal battery in which the key parameters are the voltage, power, heat flow, and efficiency as functions of the electric current and temperature difference. 5,11,15 A TEG module delivers electricity as a consequence of the Seebeck effect, but the Peltier and Thomson effects also take place because the electric current passes through the TE material located in a temperature field. 16,17 In addition, when the module is in operation, Joule heating is inevitable.…”

A three-dimensional closed-circuit numerical model of a thermoelectric generator (TEG) module has been constructed with COMSOL Ò Multiphysics to verify a module test system. The Seebeck, Peltier, and Thomson effects and Joule heating are included in the thermoelectric conversion model. The TEG model is employed to simulate the operation of a 16-leg TEG module based on bismuth telluride with temperature-dependent material properties. The module is mounted on a test platform, and simulated by combining the heat conduction process and thermoelectric conversion process. Simulation results are obtained for the terminal voltage, output power, heat flow, and efficiency as functions of the electric current; the results are compared with measurement data. The Joule and Thomson heats in all the thermoelectric legs, as functions of the electric current, are calculated by finite-element volume integration over the entire legs. The Peltier heat being pumped at the hot side and released at the cold side of the module are also presented in relation to the electric current. The energy balance relations between heat and electricity are verified to support the simulation.

“…In Ref. (Carmo et al 2011), the relationship between temperature gradient and the amount of electricity generated has been examined. The result shows that the open circuit voltage of an energy harvester increases when the temperature gradient of the harvester rises.…”
