1.3 Fuel Oil Combustion

Atmospheric nitrogen-containing particles decrease visibility. NOx can react to form nitrous oxide (N 2 O), which is a greenhouse gas, and contribute to global warming. Coal usually contains between 0.5 and 3 percent nitrogen on a dry weight basis. The nitrogen found in coal typically takes the form of aromatic structures such as pyridines and

8.7. Nitrogen Oxides (NOx) Emissions | netl.doe.gov

Jun 04, 2020 · Emissionsof sulfur dioxide (SO 2) and nitrogen oxides (NO x) from the electric power sector in 2012 declined to their lowest level since the passage of the Clean Air Act Amendments of 1990.The decline in emissions is due primarily to an increasing number of coal-fired units retrofitted with flue-gas desulfurization (FGD), or scrubbers, to coal plants switching to lower sulfur coal, and to

of nitrogen in the fuel.16 In pulverized coal combustion in a utility boiler, fuel NO x may typically contribute up to 80% of the NO x emissions.14 Formation of fuel NO x depends on the nitrogen content in the fuel and the amount of oxygen available to react with the nitrogen during coal devolatilization in the early stages of com-bustion. Accordingly, fuel NO
