Nitrogen Oxides (NOx) Primer - Babcock & Wilcox

Flue Gas Recirculation (FGR) is a widely applied technique for reducing nitrogen oxide (NOx) emissions from natural gas-fired industrial and commercial boilers, and boilers can typically operate at recirculation rates of 20-25 percent without adversely affecting

An overview on reduction of nitrogen oxides in flue gases

of nitrogen in the combustion air with excess oxygen at elevated temperatures, referred to as thermal NOx; and (2) oxidation of nitrogen that is chemically bound in the fuel, referred to as fuel NOx. For coal-fired units, thermal NOx generally represents about 25% and fuel …

Nitrogen Oxides: Pollution Prevention and Control

Nitrogen oxides (NO. x) are gaseous pollutants that are primarily formed through combustion process. While flue gas is within the combustion unit, about 95% of the NO. x. exists in the form of nitric oxide (NO). The balance is nitrogen dioxide (NO. 2), which is unstable at high temperatures. Once the flue gas is emitted into the atmosphere, most of the NO. x

NITROGEN OXIDES FORMATION in combustion processes

the biggest contribution has nitric oxide (NO) its content in flue gas is in the range of: 100 –1000 mg/m3 next is nitrogen dioxide NO 2 in proportion 5-10% of NO its content in flue gas is in the range of: 10 –100 mg/m3 N 2O has the least contribution: its content in flue gas is in the range of: 1–10mg/m3

Control of pollutants in flue gases and fuel gases

Nitrogen species in a typical flue gas under chemical equilibrium conditions • Most abundant ones λ=1.1: N 2, NO, NO 2, N 2 O λ=0.9: N 2,HCN, NH 3 • Equilibrium conc. of NO x decreases with temp.: data from flue gas with λ=1.1: T=1800 K 1200 ppm T=500 K <1ppm
