摘要
能源问题和环境问题已经成为各国不得不面对的社会问题,基于塞贝克效应设计了一种温差发电燃气烤炉,将余热转换成电能,利用燃气的冷能维持温差发电芯片冷热端温差,同时预热了燃气。搭建实验平台测试了温差发电燃气烤炉的温差发电模块温度曲线、电能输出特性和预热对烤炉热效率的提升,该温差发电烤炉可输出功率为2.9 W,燃气经预热后烤架温度平均上升31.9℃,结果表明所设计的温差发电烤炉系统较好地利用温差发电芯片的热电转化能力,可维持用电器正常运转,达到使用要求。
Energy and environmental issues have become social problems. A thermoelectric gas stove based on Seebeck effect is designed, which converts waste heat from the stove into electric energy. Combined with this design, the cold energy of gas is used to maintain the temperature difference between the hot and cold sides of the thermoelectric generator, and preheats the gas at the same time. Temperature curve of thermoelectric generator module, the power output characteristic and the improvement of thermal efficiency by preheating have been experimentally studied. The results show that the electric power supply is 2.9 W, and the average grill temperature rises by 31.9 ℃ after the gas is preheated.
