The ignition and blowout, combustion and emission characteristics of a coaxial staged combustion chamber of a natural gas turbine were experimentally tested, and the combustion and emission characteristics of the combustion chamber were numerically calculated by using the chemical reaction mechanisms of different fuels. The results showed that, the ignition fuel/air ratio decreased first and then slightly increased with the increase of inlet air flow, and the blowout fuel/air ratio decreased first and then remained unchanged with the increase of inlet air pressure. With the increase of fuel/air ratio, the temperature rise of the combustion chamber and the average temperature at the outlet of the combustion chamber gradually increased, and the NOx mole fraction gradually increased, the CO mole fraction remained unchanged, and the UHC mole fraction first decreased and then increased at the outlet of the combustion chamber. With the increase of inlet air pressure, the temperature rise and the outlet average temperature first increased and then decreased, and the mole fractions of UHC, CO decreased, and the mole fraction of NOx first decreased and then increased at the outlet of combustion chamber. With the increase of inlet air temperature, the temperature rise first increased and then decreased, the outlet average temperature gradually increased, and the mole fractions of UHC, CO gradually decreased and the mole fraction of NOx gradually increased at the outlet of combustion chamber. Compared with the single step reaction mechanism and the detailed reaction mechanism of methane, the outlet average temperature and major emissions' mole fractions calculated by the reduced reaction mechanism of natural gas had the smallest error between the corresponding experimental data. With the rise of the working condition, the high temperature area in the combustion chamber increased, the temperature rise and the outlet average temperature increased, the mole fractions of NOx and CO2 increased and the mole fraction of CO decreased at the outlet of combustion chamber.
