摘要

为了进一步提高温差发电系统的热电转换效率，从而提升其在分布式能源中的适用性，针对一种典型多级热源利用型温差发电系统，采用数值计算方法研究了不同燃烧器结构对系统的流场、温度场以及发电性能的影响，并提出了燃烧器结构的优化方案。模拟结果验证了系统级优化方案的合理性和可行性，优化后系统的流场和温度场得到较大的改善，热电模块的温度有较大提高且分布更为均匀，输出功率和发电效率提升显著。

Abstract

In order to increase the efficiency and applicability of thermoelectric generation (TEG) system in distributed energy, with the framework of numerical calculation, an optimized scheme of burner is proposed to study the influence of burner structure on flow field，temperature field and the generation performance of a typical multi-level heat source utilization TEG system. The simulative results prove the rationality and feasibility of the proposed optimization method，which indicate that the flow field and the temperature field are optimized, the temperature uniformity of the thermoelectric modules, the output power and efficiency of the system are improved.
