Research and development of new-type PCSB pulverized coal burners

The combustion stabilization problems in existing burners were analyzed with the flame propagation theory,and the potential to reduce NOx was demonstrated according to the formation mechanism of NOx.Based on this,the new design and scheme of the PCSB burner was proposed.The result shows that PCSB burner is a new kind of burner with novel idea and simple structure,which is of low NOx and stabilized combustion and developed with the principles of pulverized coal stage combustion,the positive ignition and flame propagation.In addition,the burners are of better adaptability to various coals and suitable for the application in tangential and wall-type combustion boilers.
