The use of a rice husk gasifier as a cook stove is limited to the domestic sector of developing countries primarily because it needs electrical energy to drive a blower for the gasification process. To solve this problem, we investigated the feasibility of attaching commercial thermoelectric (TE) modules made of bismuth-telluride materials to the gasifier's side wall, thereby creating a TE generator system that utilizes a proportion of the gasifier's waste heat. A rice husk gasifier TE generator (TE-RSG) having an internal diameter of 16 cm was fabricated and tested. The TE generator system consisted of two commercial TE modules, a metal sheet wall which acted as one side of the gasifier's structure and served as the hot side of the TE modules and a rectangular fin heat sink at the cold side of the TE modules. A blower was used to suck the ambient air to cool the heat sink and blow the air from the heat sink to the reactor of the gasifier. Gasification was conducted in a temperature range of 500-700°C and gasification agent, air feeding rate of 18.6 m3/h. The results revealed that the electrical power output and the conversion efficiency depend on the temperature difference between the cold and hot sides of the TE modules. At the temperature difference of approximately 60°C, the unit achieved a power output of 3.9 W and a conversion efficiency of 2.01%. Through a comparison of results between the theoretic model and the experimental system, the reasonability of this system model has been verified.

“…It is a feasible choice for remote regions where constant electric power supply cannot be relied upon. Qiu and Hayden [17,18] set up a self-powered residential heating system which integrated TE power generation system with combustion system. The electricity generated by TE modules cannot only power all electrical components for the residential central heating system, but also be used to charge batteries or provide electricity for other electrical loads.…”

“…The conversion of heat into electrical energy is one of the interesting sustainable and renewable energy re-generation systems, allowing the recovery of waste heat in many industrial and non-industrial systems [1,2]. The efficiency of thermoelectric materials is characterized by the figure of merit ZT = S²T/ȡwκ (S -Seebeck coefficient, ȡ -electrical resistivity, κ -thermal conductivity).…”
