火电厂排烟余热用于温差发电的实验研究

为了提高火力发电厂的能源利用效率以达到节能减排和保护环境的目的,进行了利用火力发电厂排烟余热进行温差发电的实验。搭建实验平台,进行了一系列的实验研究,得到了单个半导体温差发电器件在输出功率最大时的匹配负载,以及在匹配负载下改变热端温度,得到了温差发电器件的温度—功率曲线。设计了一种将该温差发电器件用于排烟余热进行发电的方案,并以徐州某电厂为例进行经济性分析。

Experimental Study of Thermoelectric Generation from Thermal Power Plant Exhaust

Experiments were carried out to improve the thermal power plant’s energy efficiency by a thermoelectric generator that recovers waste heat from the exhaust smoke to save energy and reduce emissions and protect the environment.A experimental platform was built to perform a series of experiments for the maximum output power by changing load resistances and hot side temperatures and fit the temperature-power curve.The experimental data was used to design a system which use thermo-electric generators for waste heat recovery from exhaustsmoke.The economic analysis takes a power plant in Xuzhou as an example.
