Nitrogen Oxides (NOx) Primer - Babcock & Wilcox

Fuel NOx The major source of NO x emissions from nitrogen-bearing fuels such as coal and oil is the conversion of fuel-bound nitrogen to NO x during combustion. Laboratory studies indicate that fuel NO x contributes approximately 50% of the total uncontrolled emissions when firing residual oil and approximately 75% when firing coal.

Nitrogen Oxides (NOx) Primer - Babcock & Wilcox

NO x formation in boilers. NO x (oxides of nitrogen) refers to the cumulative emission of nitric oxide (NO) nitrogen dioxide (NO 2) and trace quantities of other nitrogen-bearing species generated during combustion.Combustion of any fossil fuel generates some level of NO x due to high temperatures and the availability of oxygen and nitrogen from both air and fuel.
