NOx (or nitrogen oxide) is a chemical in automotive exhaust that gets created when the temperature inside a vehicle engine's combustion chamber exceeds 2,500 degrees Fahrenheit. It is a pollutant that helps create smog, acid rain and particulate pollution. This
Revised standards for Coal-based Thermal Power Plants . 07/12/2015 SO2 & Nitrogen Oxide - NOx will also help in control of mercury emission (at about 70-90%) as a co-benefit. Limiting the use of water in thermal power plant will lead to water conservation (about 1.5 M3/MWh) as thermal power plant is a water-intensive industry.
On the other hand, if you have a boiler or an engine that combusts fuel, then you should expect to see combustion contaminants that include nitrogen oxide (NOx), sulfur dioxide (SOx), volatile organic compounds (VOCs), carbon monoxide (CO), and particulate matter. As a third example, if you have a flour silo, you shouldnt see emissions of
