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

NOx Emissions Control Although NOx emissions from operating IGCC power plants are quite low as shown above, stricter regulations may require control to levels as low as 3 ppm in the heat recovery steam generator (HRSG) stack gas. Following is a review of both combustion-based and post-combustion NOx control methods used for NOx emissions control.

How To Calculate Nox From Coal Fire Boiler

Plant Engineering | GAS TECHNOLOGY: Boiler NOx . In many areas, industrial boiler operators face stricter regulation of NOx emissions, even with the use of clean natural gas. In some areas, operators are required to meet what are called "Ultra-Low NOx" (ULN) requirements, typically less than 10-12 ppm.

Plant Engineering | Gas Technology: Reduced boiler NOx

Apr 11, 2014 · Significant NOx emission reductions have been achieved by designing burners and boilers to avoid "hot spots", where elevated temperatures can generate excess NOx. Low-NOx burners were designed with this in mind. Properly selected, installed and operated, these can achieve emissions below 30 ppm NOx with the standard 3% excess oxygen.

Low Emission Boilers | LOW NOx | Hurst Boilers

Our boilers can burn any liquid or gaseous fuel; and come in sizes from 100 to 2,500 horsepower with pressures to 450 PSI. Hurst boilers are designed and engineered with larger furnaces, providing for inherently lower NOx emissions. To produce lower emissions, our boilers employ technologies such as; gas and air pre-mix, flue gas recirculation

Research of boiler combustion regulation for reducing NOx

Jan 10, 2005 · Power boilers can form NO X in two ways — from fuel and from temperature. Fuel NO X is formed by the reaction of nitrogen contained in the fuel with oxygen in the air and is not a problem when natural gas is the fuel. However, fuel oils can contain significant amounts of nitrogen and can account for up to 50% of total NO X emissions of power boilers.
