摘　　要：在环形高温温差发电系统的基础上,提出一种高中温耦合温差发电系统,数值研究不同燃烧器结构对系统性能的影响,获得经优化后的新型燃烧器结构。实验结果可验证模拟结果的正确性,新型高中温耦合温差发电系统发电功率明显高于单级高温发电系统,且其热电模块的温度分布更均匀,系统发电效率得到较大的提高。Based on the existing annular high temperature thermoelectric power generation system,a high-temperature and medium-temperature coupling TEG system was proposed,the influence of burner structure on TEG performance was studied with CFD numerical Simulation method,and a burner with novel optimal structure was obtained.The experiment results are in accordance with the simulation results.The output power of high-temperature and medium-temperature coupling TEG system is higher than that of the single-stage high-temperature TEG system,the hot side temperature of the TE module is more uniform,and higher system power generation efficiency is obtained.
