Alternate Solutions for Reducing NOx Emissions from

Since 20th December 2018, medium combustion plants (excluding plants and gas turbines) for new buildings, which commercial boilers fall under, with a thermal input between 1MW to 50MW must stay below NOx emissions of 100mg/NM³ (gas) or 200mg/Nm³ (oil).

Plant Engineering | GAS TECHNOLOGY: Boiler NOx Emissions

Jul 21, 2010 · 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. It is widely believed that the ULN requirements will be broadened to more areas.

NOx emissions and boilers – What you need to know

Dec 18, 2017 · NOx is a term that is used to refer to nitrogen oxides, gasses that are created during the combustion process when nitrogen in the fuel that boilers use comes into contact with oxygen in the air. The amount of NOx emissions formed in this process is affected by a variety of factors, including the amount of nitrogen in the fuel, flame

Overview of SCR Technology and Retrofitting of SCR's

Theoretically, there is no limit to the amount of NOx reduction with FGR; practically, there is a physical, feasible limit. The limit of NOx reduction varies for different fuels Ñ 80% for natural gas and 20-25% for standard fuel oils. The current trends with low NOx technologies are to design the boiler and low NOx equipment as a package.
