英文摘要：

This paper presented a small scale power generation system based on the thermoelectric conversion principle. The flammable characteristics of the small scale methane combustor used in the system were tested, and then the factors that could significantly influence the system performance were studied experimentally. The results indicated that the small combustor used in the system works steadily in a wide fuel/air flux range under a wide Equivalence Ratio （ER） range. Additionally, it could be concluded that the load resistance, ER, input energy （i.e. fuel flux） and heat transfer condition with the ambient environment will influence the output power and the total efficiency of the power generation system evidently. The maximum output power of 569 mW and the highest total efficiency of 0.55% were obtained in the experiments.
