Boiler Emissions 101 - Boiler Service | Boiler Parts

Part of the reason natural gas is now so prevalent is that it burns cooler than fuel oils and has no nitrogen in it, making it inherently a lower producer of NOx. Refineries have been mandated to reduce levels of sulfur, nitrogen and other pollutants in order to reduce emissions.

Beijing's burning issue – reducing boiler NOx emissions …

This year, Beijing plans to implement low NOx modifications on more than 7GW of gas-boiler capacity. The issue of NOx emissions in gas combustion is mainly down to so-called thermal NOx, which is the reaction of nitrogen and oxygen molecules present in the combustion air. Thermal NOx formation varies exponentially with flame temperature, so the

NOx Class 6 | Nitrogen Oxide Emissions | Ideal Boilers

26/9/2018 · Nitrogen plays no part in the combustion process of natural gas and would, ideally, pass through the boiler without reaction. However, there are three primary processes that create NOx during natural gas combustion: thermal NOx; fuel NOx; and prompt NOx. (See box-out for an explanation of the oxides of nitrogen.)
