Thermal Electric Power Generator
~ Custom-made to your specification ~
The TE power module features:
♦ Maximum thermoelectric conversion efficiency ≅ 5%@ΔT= 200°C (Tc=30°C)
♦ Industry waste heat recovery (< 300°C)
ITRI's TE team deep-rooted in new materials development has also established full spectrum capabilities of materials design, processing technologies, as well as characterization technics. For more than 10 years, ITRI has collaborated with world class institutes such as Ioffe, one of Russia's largest research institutions, and local steel plants to accumulate core competence from profound knowledge to hands-on experience of TE power generator.
We are able to prepare wide range of TE materials, including low temperature TE of Bi2Te3 (P-type (Bi,Sb)2Te3, N-type Bi2(Te,Se)3); middle temperature's PbTe, GeTe, TAGS; and high temperature’s half-heusler type (MNiSn, M=Zr, Hf, Ti). In addition, we're also working on advanced low dimensional thermoelectric materials such as:
◊ Bi-Te based thermoelectric thin film (sputtering, electroplating)
In summary, the following is the list of our core competence;
Upon years working on conventional Bi-Te based TE material, we have accumulated the experience on pilot production of zone-melting ingot with 24mmΦx 2500mmL in dimension and ZT values between 0.95~1.1. A high homogeneity property along the zone-melting bar, with a variation of power factor less than 5%, empowers our capability to a level of commercial production of TE power generation modules.
Success Cases:Industrial waste heat recovery by ITRI’s TE power generator
A 200W small scale system was installed in a local steel plant with the capacity of 1728 kWhr/year. In addition to the power generation, the on-site working temperature was lowered by 20°C (from 50°C->30°C). A rough calculation gives an estimation of 95 G kcal/year waste reduction and 0.11 bWhr/year of power generation, which is corresponding to a 140k tons of CO2 reduction, and equally to 370 Taipei's Ta-An forest park.
