Nitrogen oxides - Products and effects of combustion

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.

NOx - Wikipedia

Emission of Nitrogen Oxides - NOx - when burning different types of fuels: 1) note that the emission varies widely depending on application temperatures and air/fuel ratios. In general - higher combustion temperature and higher air/fuel ratios increases NOx emissions. 2) zero emission for hydrogen is a theoretically value.

Nitrogen Oxides - an overview | ScienceDirect Topics

Nitrogen oxides produced in combustion processes of boiler furnaces are a dangerous environmental pollutant. The amount of nitrogen oxides emitted by the boiler depends mainly on the fuel characteristics, the furnace type determining the temperature level in the combustion region, and the oxygen concentration in the initial section of the flame.

Mar 30, 2021 · The combustion temperature of the boiler is too high, causing the N2 in the air to be oxidized to NOX. 1 The analysis of Zhongyuan Coal Industry does not test the nitrogen content, but according to the actual production data, as much as possible to use the coal that produces nitrogen oxides.

Reducing nitrogen oxides in the flue gases from gas/oil

Nitrogen Oxides - Nitrogen oxides formation occurs by three fundamentally different mechanisms. The principal mechanism of NOx formation in natural gas combustion is thermal NOx. The thermal NOx mechanism occurs through the thermal dissociation and subsequent reaction of nitrogen (N2) and oxygen (O2) molecules in the combustion air.

Sep 26, 2018 · Nitrogen plays no part in the combustion process of natural gas and would, ideally, pass through the boiler without reaction. However, there are three primary processes that create NOx during natural gas combustion: thermal NOx; fuel NOx; and prompt NOx. (See box-out for an explanation of the oxides of nitrogen.)
