针对工业余热存在形式多样、数量巨大的特点,设计工业余热温差发电系统,并测试不同温差下单元发电器的输出特性。结果表明:在260℃温差时,单个温差发电器的输出功率可达155.85 W;当热端温度为260℃时,温差发电机转换效率可达4.389%。
In view of the variety and huge quantity of industrial waste heat,a thermoelectric generation system from industrial waste heat was designed. Besides,the output property of single thermoelectric generator was tested under different temperature difference(ΔT). The result shows that the output power of a single thermoelectric generator can reach 155.85 W when ΔT =260℃,and the conversion efficiency of thermoelectric generation is about 4.389%when the hot side temperature is 260℃.
