摘　　要：热光伏系统是将燃烧产生的热能转变为辐射能并通过光伏电池转变为电能的系统,为提高能量的利用效率,可使用回热器进行尾气热量的回收。通过FLUENT仿真软件,对回热器内部对流与导热的模拟,得出仿真结果,比较和分析两种回热器的烟气和空气出口温度、有效度的变化。仿真结果表明:与实验结果相比,仿真数据比较真实可靠;Ⅱ型回热器大大提高了的空气出口温度约220℃,而降低了改进前回热器的烟气出口温度,提高了改进前回热器的有效度e,大大提高了改进前回热器的传热性能。By using the thermo-photovoltaic（TPV） technology,thermal radiation can be converted into electricity through photovoltaic cells.The recuperative system of TPV system can reduce heat loss as a result of high-temperature gases and improve the efficiency of the system.Through the simulation of the internal heat convection and heat conductivity of recuperators by FLUENT software,the changes of flue gas and air temperatures,and the effectiveness of recuperators are compared and analyzed.The results of experimental study show that the Ⅱ recuperator increases the air exit temperature by about 220 ℃ and increases the effectiveness by about 0.1 of the Ⅰ recuperator,decreases the gas exit temperature of the Ⅰ recuperator,and greatly improves heat transfer performance of the old recuperator.
