Abstract: The control for the pollutants emission from power plant by the government is becoming more and more stringent. Under the premises of boiler combustion stability and the high combustion efficiency, it is very important to control the NOx emission. The generative mechanisms of the NOx were introduced. The influences of the burners with different structure on the NOx analyzed. The application of the NOx restraining technology in Inner Mongolia Huadian Baotou Power Generation Corporation Limited was expounded.
