8NH3+6NO2=7N2+12H2O
4NH3+3O2=2N2+6H2O
4NH3+5O2=4NO+6H2O
2NH3 can be reversed to generate N2+3H2
The purpose of denitration is to turn the Nitrogen oxides into the normal components of the air (N2 and H2O) where the valence of nitrogen oxides +2 +4 valence, need to be reduced to 0 valence, the valence of ammonia -3 valence, can be reflected, the products are harmless and non-polluting, purely hand-typed, to give praise
