Influence of Change of H/O Mixture Ratio on Combustion in the Combustor of the Micro Thermophotovoltaic System

Article Preview

Abstract:

The change of H/O mixture ratio has affect on the combustion of H/O mixed gas in the micro combustor, and the temperature distribution of the micro combustor wall are researched in this paper, when the mixed gas flux is different in the combustor of the micro thermophotovoltaic system. The result of the test indicates that H/O mixed gas can combust stably in the micro combustor. As mixed gas flux is 3.92g/h and H/O mixture ratio is 2, the temperature of the micro combustor wall is about to 1100K, which matches work requirement of the micro thermophotovoltaic system.
