Low-NOx Burners for Industrial Boilers | HPAC

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.

Plant Engineering | Gas Technology: Reduced boiler

In older industrial boilers, NOx emissions were sometimes relatively high because of boiler design and burner performance characteristics. In boilers, high NOx emissions can be a result of two issues. NOx levels increase dramatically where temperatures in exhaust gas streams rise significantly above 2200°F.

2018-6-13 · Thermal NOx is produced from the oxidation of nitrogen (N2) at temperatures above 1500°F. Thermal NOx is the primary source of NOx formation from natural gas and distillate oils because these fuels are generally lower or devoid of nitrogen. Fuel NOx, on the other hand, results from oxidation of nitrogen organically bound in the fuel.

2002-1-25 · The formation of NOx. NOx emissions do not form in significant amounts until flame temperatures reach 2800 F. Once that threshold is passed, however, any further rise in temperature causes a rapid increase in the rate of NOx formation (A). NOx production is highest (B) at fuel-to-air combustion ratios of 5–7% O2 (25–45% excess air).

Boiler Emissions 101

The higher the temperature, the more created. Since oil contains trace amounts of nitrogen and burns hotter than natural gas, oil firing inherently creates more NOx than natural gas. Why it's controlled: NOx is a precursor to ground level ozone, when combined with sunlight breaks down to ozone (O3) and nitrogen. Ozone performs a vital
