A new system for converting combustion heat into electric power was proposed on the basis of countercurrent burner with thermoelectric element embedded in a wall separating incoming fresh mixture and combustion products. The wall serves as heat exchanger between combustion products and the fresh mixture. Numerical simulations showed that almost whole combustion heat may be transferred through the thermoelectric element in such system and the total thermal efficiency attained a value close to the conversion efficiency of the thermoelectric device itself.

This research studies the alternative way of electricity generating from the waste heat of economy oven by using 4 modules of thermoelectric modules. The hot side of thermoelectric module is attached to the heat plate while the cold side is installed on the rectangular, plate-fin heat exchanger. Variety of system adjustments were used during this study in terms of finding the maximum electric power rate. Adjusting the heating value and the electrical resistance to the thermoelectric was the procedure in this study. From the research, we found out that at the temperature of 200°C on the heat pad, the released maximum electric current was 4.5 W. The percentage of heat converting to electric current was 11.9%, with the 0.84 A and 5.35 V. The efficiency of the economy oven was 23.20%, and comes up to 23.39% while generating power via thermoelectric module.

A compact water-cooled thermoelectric generator (TEG) based on a portable gas stove was designed and analyzed to supply electricity in off-grid scenarios. The TEG incorporates a newly designed heat collector, eight thermoelectric (TE) modules, and a radiator to ensure its portability (5.9 kg) and sufficiency of electric power (12.9 W). Detailed measurements and discussions on power load feature and TE efficiency are presented. Experiments showed that the power generation capability of the proposed TEG is compromised by its compactness over previous water-cooled TEGs. A theoretical model incorporated with heat leaks from various origins has been developed to illustrate that the designed TEG exerts the potential of every TE module, and to reveal the proportion of various heat fluxes. The predicted electric power, various heat fluxes, and TE efficiency agree well with experimental data. The limitations of TE efficiency and the nonlinearity caused by Joule heat are discussed quantitatively.
