Low Nitrogen Oxides Superconducting boiler

Boiler Combustion | CleanBoiler.org

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.

Ultra-low nitrogen oxides (NOx) emissions combustion in

Apr 11, 2014 · Significant NOx emission reductions have been achieved by designing burners and boilers to avoid "hot spots", where elevated temperatures can generate excess NOx. Low-NOx burners were designed with this in mind. Properly selected, installed and operated, these can achieve emissions below 30 ppm NOx with the standard 3% excess oxygen.
