1.4 Natural Gas Combustion - US EPA

1.4.3 Emissions3-4 The emissions from natural gas-fired boilers and furnaces include nitrogen oxides (NOx), carbon monoxide (CO), and carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), volatile organic compounds (VOCs), trace amounts of sulfur dioxide (SO2), and particulate matter (PM). Nitrogen Oxides -

Issues on Nitrogen Oxides Concentration Reduction in the

Jan 01, 2015 · In burning the fossil fuels in boilers the nitrogen of the air, interacting with oxygen, forms oxides: NO Ñ… = NO + NO 2 + N 2 О. The main share of NO Ñ… (95-99 %) generated in the combustion products of steam and water-heating boilers is carbon monoxide NO. Dioxides NO2, nitrous oxide N 2 O are produced in much smaller quantities.

Reduction of nitrogen oxides from boiler flue gases

During the fossil fuel combustion process in gas-tube boilers furnaces, nitrogen contained in the air and fuel actively interacts with oxygen to form nitrogen oxide NO, dinitrogen oxide N 2O, and nitrogen dioxide NO 2. The most of NOх produced in the exhaust products combustion process (95-99 %) in gas-tube boilers furnaces accounts
