Boiler Combustion | CleanBoiler.org

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.

Analysis: Gas boilers and NOx: the hidden emitter

Air pollution, specifically nitrogen oxides (NO x) emission from gas boilers, could spike over the course of a winter spent working from home, potentially compromising the UK's ability to meet legally binding air quality targets, a new report finds [1]..
