NOxkontroll
NOxkontroll refers to the set of measures and technologies used to limit emissions of nitrogen oxides (NOx) from combustion sources. NOx, which includes nitric oxide (NO) and nitrogen dioxide (NO2), are formed when fuels burn at high temperatures and contribute to smog, acid rain and respiratory health problems. The concept covers both transport and stationary sources such as vehicles, power plants, boilers and marine engines.
Common sources of NOx include road transport (especially diesel engines), electricity and heat production, industrial boilers
Primary measures focus on controlling the combustion process. These include optimizing combustion conditions to lower peak
Secondary aftertreatment methods treat exhaust after it leaves the engine or boiler. Selective catalytic reduction (SCR)
Regulatory frameworks (for example, EU emission standards and US EPA rules) drive NOxkontroll adoption, often requiring
