What is the difference between fuel NOx and thermal NOx ?
Posted On: Nov 17, 2022
Thermal NOx : Nitrogen and oxygen combine in the combustion air to form thermal NOx at high temperatures in a flame. The majority of the NOx formed during the combustion of gases and light oils is thermal NOx.
Fuel NOx: Whereas fuel combustion is formed by the combustion of oxygen in combustion air and nitrogen bound in fuel. Gaseous fuels do not create any serious problems but the oils containing fuel-bound nitrogen, and fuel NOx can go up to 50% of the total NOx.
