How to Reduce NOx: A Guide to Low Emission Boilers

· Low NOx burners can reduce your NOx emissions to 30 pm This equipment uses FGR and can maintain 3 to 5% excess O2 with strong controls Low NOx burners offer good flame stability and turndowns that are less than the ratio of 8 to 1 With Ultra Low NOx burners you can achieve emissions anywhere between 7 to 15 ppm These burners use adjusted fuel/air ratios FGR as well as staging to

Natural Gas Fired Boilers

The principal mechanism of formation while firing is thermal which is very different than firing coal with a modern where is mostly fuel Thermal occurs through the thermal disassociation and subsequent reaction of nitrogen (N2) and Oxygen (O2) molecules in the combustion air which is approximately 78% N2
