LågNOxbränslar

LågNOxbränslar, or low-NOx fuels, are a category of fuels or fuel additives designed to reduce the formation of nitrogen oxides (NOx) during combustion. NOx emissions are a significant air pollutant, contributing to smog, acid rain, and respiratory problems. The formation of NOx primarily occurs at high temperatures in the presence of nitrogen and oxygen.

Technologies and fuel compositions that qualify as lågNOxbränslar aim to mitigate these high-temperature reactions. This can be achieved through several methods. One common approach involves modifying the fuel itself by removing or reducing nitrogen content. Another strategy is the use of additives that interfere with the chemical reactions that produce NOx. These additives can act as catalysts or radical scavengers.

Furthermore, the term can also encompass fuels used in conjunction with combustion modifications that inherently lower NOx production, such as staged combustion or the introduction of inert gases. The goal is to achieve cleaner combustion processes with reduced environmental impact. Applications for lågNOxbränslar are found across various sectors, including industrial boilers, power plants, and internal combustion engines, wherever emission control is a priority. Their development is driven by increasingly stringent environmental regulations and a growing awareness of the health and ecological consequences of NOx pollution.
