What is NOx - And Why Control It?
We proudly promote the Nationwide Boiler CataStak™ Selective Catalytic Reduction (SCR) System for single-digit NOx emissions on package boilers and other fired equipment. Have you ever wondered exactly what NOx is, and, why reducing NOx emissions and your carbon footprint is important?
NOx refers to nitrogen oxides. It is a generic term for a group of highly reactive gases containing oxygen and nitrogen in varying amounts. NOx forms when fuel is burned at high temperatures, like in a burner combustion process. Package boilers, fired heaters, gas turbines, heat recovery steam generators, and other fired equipment will produce varying levels of NOx, depending on the type of fuel, the burner construction and arrangement, and if any SCR technology is being used.
In short, reducing NOx emissions into the atmosphere will reduce a number of health and environmental hazards linked to the harmful pollutant. NOx has been linked to ground-level ozone, acid rain, water quality deterioration, global warming, and a number of significant respiratory issues.
The EPA and state air boards have been instrumental in the reduction of stack emissions since the 70’s, and Nationwide Boiler has been using and selling CataStak™ SCR systems to continue the trend. Check out this informative article for more detailed information on the harmful effects of NOx and how the EPA is working to control it.
