Abstract: Micro-thermphotoelectricity(MPTV) system is a new type of micro-power mechanical-electrical system. This article analysis and expounds the infections of the factors that the different quantity of airflow of admixture of hydrogen and oxygen to the combustion status, the distributing of temperature of the wall of tube and the exit in the MPTV combustion. The experiment proves that the admixture of hydrogen and oxygen is easily burning steadily in the micro-combustion. The temperature of the wall of the micro-combustion may attain 1 300 K when the flux is 2.167×10–5 m3/s and the ratio of mixture is 2∶1.
