In order to study the produce and reduce characteristics of the NOx in the process of fuel combustion and combustion gas denitrogenation, the frozen characteristics of the NOx and their related components of uniform gases at high temperature of 1400 - 2600 K in a quenching rate of 0.2×108 -0.4×108 K/s are studied. The effects of cooling rate on the results of analysis of NO and NO2 in gases sampled by sampling probe are discussed. The mathematical models and chemical kinetic models which express the relaxation process of gas compositions in nonequilibrium condition of quenching process are constructed.
