Prediction of NOx Emissions [PDF]

open access: yesVolume 2: Coal, Biomass and Alternative Fuels; Combustion and Fuels; Oil and Gas Applications; Cycle Innovations, 1981
A procedure has been developed for predicting the formation of NOx in gas turbine combustion systems operating at various conditions and on a variety of fuels, if the NOx produced by that engine is known for any one combination of fuel and operating condition.

Photochemical emission and fixation of NOX gases in soils [PDF]

open access: yesScience of The Total Environment, 2020
Gaseous nitrogen oxides (NOx), which result from the combustion of fossil fuels, volcanic eruptions, forest fires, and biological reactions in soils, not only affect air quality and the atmospheric concentration of ozone, but also contribute to global warming and acid rain. Soil NOx emissions have been largely ascribed to soil microbiological processes;

The influence of emission changes on ozone concentrations and nitrogen deposition into the southern North Sea

open access: yesMeteorologische Zeitschrift, 2011
The impact of changes in amount of emission for NOx (Nitrogen monoxide NO + Nitrogen dioxide NO2) and NMVOC (Non Methane Volatile Organic Compounds) on concentrations of ozone (O3), NOx, nitric acid (HNO3) and on nitrogen deposition in the area of the ...

A NOx Emission Model Incorporating Temperature for Heavy-Duty Diesel Vehicles with Urea-SCR Systems Based on Field Operating Modes

open access: yesAtmosphere, 2019
The selective catalytic reduction (SCR) is the most commonly used technique for decreasing the emissions of nitrogen oxides (NOx) from heavy-duty diesel vehicles (HDDVs). However, the same injection strategy in the SCR system shows significant variations

Biochar addition can reduce NOx gas emissions from a calcareous soil

open access: yesEnvironmental Pollutants & Bioavailability, 2019
The effect of biochar (BC) addition on NOx gas emissions was investigated from a calcareous soil. Application rates of zero (BC0), 1 (BC1), 2 (BC2), 5 (BC5), and 10 (BC10) percent weight/weight were used.
