low nox gas fired boiler

Boiler upgrade for emissions reduction | GE Steam Power

Jan 09, 2013 · 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.

How to Reduce NOx: A Guide to Low Emission Boilers

Oct 12, 2016 · The majority of NOx emissions are the result of nitrogen in the fuels used or from nitrogen in the combustion air, which is thermal NOx. For oil-fired boilers and natural gas-fired boilers, thermal NOx comprises most NOx produced by industrial boilers. Thermal NOx emissions will increase as peak flames temperatures increase.

1.4 Natural Gas Combustion - US EPA

from natural gas-fired boilers are flue gas recirculation (FGR) and low NOx burners. In an FGR system, a portion of the flue gas is recycled from the stack to the burner windbox. Upon entering the windbox, the recirculated gas is mixed with combustion air prior to being fed to the burner. The recycled flue gas
