[0002] A low-nitrogen burner is a device used to improve combustion efficiency and reduce pollutant emissions. Its main goal is to reduce the generation of nitrogen oxides, thereby reducing the concentration of nitrogen oxide emissions during the combustion process to meet environmental protection requirements. The design of a low-nitrogen burner includes adding a blower, an induced draft fan, a frequency converter and a control valve, as well as a complex system integrating multiple circuits. These components work together to effectively combine clean energy with the burner to provide more efficient heat energy for boilers or other related equipment.
