advances in reduction of nox and n2o1 emission formation

Advances in reduction of NOx and N2O1 emission formation

The major percentage of NO x formed in oxy-fluidized bed condition is caused by the oxidation of nitrogen content that is chemically bound to the fuel.. The N content in coal can range from 0.5 wt%–2.5 wt%, whereas 0.1 wt% (wood)–0.5 wt% (agricultural residues) in biomass , as shown in Table 2.Nitrogen is chemically bounded in the form of pyridines, quinolones, iso-quinolines, amines
