Zeldovich Mechanism

From the above table it is clear that emission can be reduced by decreasing the temperature.
(Figure 39.2)
Thermal are formed by simple heating of oxygen and nitrogen. The radical ‘N' can react with to form NO. Thermal NO contribution is low till 1300 K and beyond which it increases rapidly. The thermal mechanism consists of the following two chain reactions.
