The pollution of NOx to the environment and the hazard to the human body are well known.
The nitrogen oxides produced during the combustion process in gas burners are mainly NO and NO2, which are commonly known as nitrogen oxides NOx. A large number of experimental results show that the nitrogen oxides discharged from the combustor are mainly NO, and the nitrogen oxides are about 95 percent on average, while the nitrogen oxides NO2 are only about 5 percent. The NO produced by the combustion of typical fuels comes primarily from two areas: firstly, nitrogen in combustion air is oxidized in the combustion process; secondly, the nitrogen contained in the fuel is re-oxidized after thermal decomposition in the combustion process, the nitrogen is the main source of NO, the NO is called as 'thermal reaction NO', the nitrogen is called as 'fuel NO', and a small amount of 'instantaneous NO' exists.
