Abstract

Aiming at solving the problem of low energy conversion efficiency due to high energy loss in micro-combustion power system, this work innovatively proposed a two-stage thermophotovoltaic-thermoelectric energy conversion system. The effects of the inlet velocity and the equivalence ratio on the energy conversion efficiency of the two-stage thermophotovoltaic-thermoelectric energy conversion system are investigated. The results indicate that two-stage thermophotovoltaic-thermoelectric energy conversion system significantly alleviates the problem of large energy loss in the micro-combustion power system and improves the energy output and energy conversion efficiency of the micro-combustion power system. As the inlet velocity increases, the total output efficiency of the micro-photovoltaic module, thermoelectric module and the overall system decreases. Under the H₂/air flow condition with an inlet velocity of 6 m/s and an equivalence ratio of 1.0, the total system reaches its a maximum energy conversion efficiency of 5.05% and generates an output power of 6.17 W.

一种新型的基于微燃烧的两级热光伏热电系统

针对微燃烧电力系统能量损失大、能量转换效率低的问题，创新性地提出了一种两级热光伏-热电能量转换系统。研究了入口速度和等效比对两级热-光电-热电能量转换系统能量转换效率的影响。结果表明，两级热光伏-热电能量转换系统显著缓解了微燃烧电力系统能量损失大的问题，提高了微燃烧电力系统的能量输出和能量转换效率。随着入口速度的增加，微光伏组件、热电组件和整个系统的总输出效率降低。在入口速度为6 m/s、等效比为1.0的H2/air工况下，整个系统最大能量转换效率为5.05%，输出功率为6.17 W。
