Boiler System: Retrofit a Boiler to Meet Low Nox Emission
Low NOx burners commonly achieve this by either flue gas recirculation or a lean premix of fuel and air. Flue gas recirculation (FGR) recirculates exhaust gases back into the combustion chamber. Because flue gas is both cooler and has substantially reduced oxygen concentrations, this can dramatically reduce NOx concentration in emissions. Retrofit
