Low Nitrogen Oxides Superconducting boiler Related Information


Dec 18, 2017 · NOx is a term that is used to refer to nitrogen oxides, gasses that are created during the combustion process when nitrogen in the fuel that boilers use comes into contact with oxygen in the air. The amount of NOx emissions formed in this process is affected by a variety of factors, including the amount of nitrogen in the fuel, flame temperature, combustion air temperature and excess air levels.

Section 4 NO Controls x - EPA

Nitrogen oxides (NO. x) are gaseous pollutants that are primarily formed through combustion process. While flue gas is within the combustion unit, about 95% of the NO. x. exists in the form of nitric oxide (NO). The balance is nitrogen dioxide (NO. 2), which is unstable at high temperatures. Once the flue gas is emitted into the atmosphere
