Abstract: In this paper,the application of oxygen-enriched combus tion technology in ceramic kiln was analyzed and evaluated.Analys is showed that the flame temperature rose nonlinearly with the concentration of oxygen increas ing; the molecules of CO₂ and H₂O water vapor enhanced radiation, and heat efficiency was greatly heightened;NO_x formation had a rapid increase first and then declined rapidly.In the meanwhile,the exces s air coefficient,energy conservation and the structure of the kiln were also discus sed.

Keywords: oxygen- enriched combus tion technology, ceramic Kiln, energy conservation
