Boiler Combustion | CleanBoiler.org

Flue gas recirculation, or FGR, is the most effective method of reducing NOx emission from industrial boilers with inputs below 100 MMBtu/hr. FGR entails recirculating a portion of relatively cool exhaust gases back into the combustion process in order to lower the flame temperature …

Boiler Emissions 101 - Boiler Service | Boiler Parts

Oct 12, 2016 · 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.

With a 100-million-Btuh-fuel-input gas boiler, the average emission factor for an uncontrolled burner is roughly 85 ppm; for a low-NOx burner, it is 42 ppm, and for a low-NOx burner with FGR, it is 26 ppm.1 Keep in mind these are average emissions; they are not regulation requirements and are not to be used as a basis for an air-permit application.
