In order to give full play to the low pollution emission characteristics of the low-swirl combustion technology, the influence of oxygen concentration change on low-swirl combustion was investigated experimentally. Based on the low swirl burner, using propane as fuel, by changing the CO2 mass flow rate through the system to adjust the premixed oxygen concentration and by controlling the air flow rate out of the nozzle, gas ratio and premixed oxygen concentration, the impact of oxygen concentration on low-swirl premixed combustion in flame form, combustion flame temperature and combustion emission product NOx was explored. Under the conditions of the test system, the lowest oxygen concentration can be achieved at the flow rate of 3.0 m/s at the nozzle, the gas ratio of 0.65, and the lowest critical oxygen concentration of 17.43%. It was found that the limit of fuel flameout increased linearly with the increase of air velocity at nozzle. With the decrease of oxygen concentration, the central incompleteness of low-swirl combustion became smaller and the flame stability of combustion nozzle became stronger. The overall temperature of the flame showed a decreasing trend. The emission of NOx from combustion was gradually reduced.
