Low nitrogen burner: the best combustion parameters can be obtained by adjusting the combustion air and combustion head. Low nitrogen burner and low NOx burner refer to the burner with low NOx emission during fuel combustion. The use of low NOx burner can reduce the emission of NOx during combustion. The oxides of nitrogen produced in the combustion process are mainly no and NO2, which are generally called NOx.

   No formed during combustion can react with intermediate products containing nitrogen atoms to reduce no to NO2. In fact, in addition to these reactions, no can also form NO2 with various nitrogen-containing compounds. When the reaction reaches chemical equilibrium in the actual combustion device, the ratio of [NO2] / [no] is very small, that is, there is little conversion of no to NO2, which can be ignored. Combustion technology for reducing NOx NOx is produced by combustion, and combustion methods and combustion conditions have a great impact on the generation of NOx. Therefore, NOx can be reduced by improving combustion technology.

   Low nitrogen burner usually refers to the burner with NOx emission of 30 ~ 80 mg.

   Low nitrogen burners are often based on the following technologies:

   1. Electronic proportional regulation and oxygen content control technology to accurately control oxygen content;

   2. Fully premixed surface combustion technology to reduce flame temperature and achieve full combustion;

   3. FGR flue gas recirculation technology to reduce flame temperature and oxygen content;
