Abstract: This paper studys the impact of oxygen-rich combus tion technology to shuttle kiln.The results show that with oxygen concentration increase from 21% to 30% ,the total concentration of CO and NO obvious ly decrease ,and then have a s low increase;The energy-saving effect is obvious ly when the concentration of oxygen at 24% to 27%,but 30% is not obvious ly;The actual flue gas volume and the concentration of oxygen is inversely proportional, and exces s air coefficient is proportional。

Keywords: Oxygen- rich combus tion technology, shuttle kiln, energy saving, exces s air coefficient
