Low nitrogen burner and low nitrogen oxide burner

Low NOx burners and low NOx burners refer to burners with low NOx emissions during fuel combustion. The use of low NOx burners can reduce nitrogen oxide emissions during combustion. The nitrogen oxides produced in the combustion process are mainly NO and NO2, and these two kinds of nitrogen oxides are usually referred to as nitrogen oxides NOx. A large number of experimental results show that the nitrogen oxides emitted by combustion equipment are mainly NO, accounting for about 95% on average, while NO2 only accounts for about 5%. The NO produced by the combustion of ordinary fuels mainly comes from two aspects: one is the oxidation of nitrogen in the air used for combustion (combustion air); the other is the thermal synthesis and re-oxidation of nitrogen compounds contained in the fuel during the combustion process. In most combustion installations, the former is the main source of NO, we call this type of NO "thermal reaction NO", the latter is called "fuel NO", and there is also "prompt NO".
