Oxides of Nitrogen

How Oxides of Nitrogen are formed and controlled.

How are Oxides of Nitrogen formed?

Whenever anything is burnt in air, oxides of nitrogen are formed. This is because the air we breathe is made up of nitrogen (78%) and oxygen (21%) and these combine when energy from combustion is available. Nitrogen dioxide, and nitric oxide are both oxides of nitrogen and together referred to as NOx.

How are Oxides of Nitrogen emissions controlled?

The first stage of the gas cleaning process starts in the boiler system using Selective Non-Catalytic Reduction (SNCR) to inject ammonia into the furnace. The ammonia reacts with the Oxides of nitrogen to produce nitrogen, and water.
