“…Other experimental campaigns were performed by Liu et al [21], where several materials and boundary conditions were assessed, obtaining a maximum 500 W power output for a 96 TE module configuration. Sornek et al [22], developed a feasibility study on the potential utilization of TE power generator applied to stove-fireplaces with heat accumulation systems. In their study the maximum experimental power obtained was of 6 W, achieved in a representative designed test rig.…”

The growing demand for electricity produced from renewable sources and the development of new technologies for the combustion of biomass, arose a growing interest on the possible coupling of thermoelectric modules with stove-fireplaces. The current thermoelectric generators have a solid structure, do not produce noise, do not require maintenance and can be used for the recovery of waste heat or excess, at the same time they hold a very low conversion efficiency and they need an adequate cooling system. Nevertheless, they still hold a cost, which is still too high to make them attractive. Nonetheless, if the modules are applied to a heat source which otherwise would be wasted, the attractiveness of the solution certainly rises. In this study, a thermodynamic analysis of a stove-fireplace is presented, considering both combustion process and the flame – walls heat transfer of the. A design solution for a concentrator device to funnel the wasted heat from the fireplace to the thermo-electric modules is also presented.

“…The second one is conversion of thermal energy into electrical energy, which is obtained from the gas-fired heating systems that heats by using electrical energy. At the combustion surfaces of solid fuel boilers, TEG works have been made by using the empty surfaces at the flue exits [7][8][9][10][11]. In a TEG study on flue gas, the probability of thermoelectric power generation was investigated by using waste flue gas in small-scale pellet boilers.…”

Gas-fired combi boilers are commonly used to meet the need for heating and general-purpose hot water in developing countries. In this study, a thermoelectric combi boiler generator (TECBG) was developed. When the boiler is operated, cold water flows through the cold surface of TECBG and enters the boiler. In the same way, it is used by flows through the hot surface of TECBG in heated water. Thus, temperature difference occurrs between the surfaces of TECBG. The temperature difference is converted into electrical energy by Seebeck effect. The proposed system was implemented on a domestic combi boiler. The maximum temperature difference between the designed system and the TECBG surfaces was recorded as 48 • C. 12V9AH battery was used to charge through a DC-DC charge regulator. About 14.28 Wh power was generated by the TECBG when the temperature difference of the TECBG, current, and voltage were 48 • C, 1.18 A, and 13.8 V, respectively. The electrical energy consumed by the combi boiler was measured as 115 Wh. Although the obtained energy is not quite high, it is an important gain in terms of energy efficiency because according to data recorded in Turkey, there are 15 million combi boiler users. Assuming that a single heating boiler runs for 4 h, it is possible to produce 306.6 GWh/year, derived from 14.28 Wh × 4 h × 365 days × 15,000,000 heating boiler. The proposed system provides significant advantages and thus can decrease power consumption.
