Control of Nitrogen Oxide Emissions: Selective Catalytic

Jul 09, 1997 · reduce emissions of oxides of nitrogen (NOx) from existing coal-fired utility boilers. NOx is an acid rain precursor and a contributor to atmospheric ozone formation, which is a health hazard and is also related to smog formation. NOx emissions are regulated under the provisions of the Clean Air Act and particularly the Clean Air Act Amend-

NOx emissions and boilers – What you need to know

Dec 19, 2019 · The chapter presents the issue of reducing mercury and nitrogen oxides emissions from the flue gas of coal-fired boilers. The issue is particularly relevant due to the stricter regulations regarding exhaust gas purity. A brief review of the methods for reducing Hg and NOx emissions has been made, pointing out their pros and cons. Against this background, the results of the authors' own

Nitrogen Oxides Emission Control Options for Coal-Fired

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 x formation can be re-duced by switching to, or cofiring with, fuel with lower nitrogen content and/or by limiting oxygen availability

Reducing nitrogen oxide emissions in boilers at moistening

Feb 01, 2012 · Coal is the most popular fuel used in power plants due to its low cost and availability. However, the emission of the nitrogen oxides during coal combustion is a significant pollutant source in the environment (Hill and Smoot, 2000). The main driver for investigations into modeling NO x emissions from coal fired utility boilers is two-fold. On
