[Abstract]:In order to reveal the mechanism of catalytic hydrogen combustion in micro combustor, a mathematical model of catalytic hydrogen combustion in micro combustion turbine engine was established according to the basic laws of mass conservation, momentum conservation, component conservation and energy conservation. Coupled with the detailed chemical reaction mechanism of surface catalysis, the combustion of micro combustion chamber of micro combustion turbine engine with different excess air coefficient n was simulated and analyzed. The results show that the inlet angle and inlet velocity of the mixed gas in the micro combustor have no obvious effect on the flue gas temperature at the outlet of the micro combustor, and when n 1.0, the outlet flue gas temperature increases and the pressure of the combustor increases, and when n 鈮，
