oksygenbrænding

Oksygenbrænding, often referred to as oxygen combustion or pure oxygen combustion, is a process where a fuel is burned in an environment of pure oxygen rather than in air. Air is approximately 21% oxygen, with the majority being nitrogen. By eliminating the inert nitrogen, the combustion process becomes significantly more intense and efficient.

This increased intensity leads to higher flame temperatures and faster reaction rates. The absence of nitrogen also means that there are fewer byproducts formed, such as nitrogen oxides (NOx), which are common pollutants in air combustion. This can be advantageous in certain industrial applications where minimizing emissions is crucial.

Oksygenbrænding finds applications in various industries. It is widely used in metal cutting and welding, where the high temperatures generated by pure oxygen facilitate rapid melting and fusion of metals. In the glass manufacturing industry, oksygenbrænding is employed in furnaces to achieve higher temperatures, leading to faster melting of raw materials and improved energy efficiency. It is also utilized in waste incineration processes to increase combustion efficiency and reduce the volume of waste.

The primary advantage of oksygenbrænding is its enhanced thermal efficiency and higher flame temperatures. However, it requires a reliable source of pure oxygen, which can be costly to produce or procure. Safety considerations are also paramount, as the presence of pure oxygen can significantly increase the flammability of materials and the risk of fire or explosion.
