How is NOx Formed | CleanBoiler.org

How is NOx Formed. In industrial boilers, NOx is primarily formed in two ways: Thermal NOx is formed when nitrogen and oxygen in the combustion air combine with one another at the high temperatures in a flame. Thermal NOx makes up the majority of NOx formed during the combustion of gases and light oils. The rate of NOx formation generally
