Zinchenko A. Kinetics of NOX formation and quenching in high frequency induction plasma

The object of research – chemically-pure RFI discharge air plasma of with a power more than 50 kW. The subject of the study is physical-chemical processes of generation of nitrogen oxides both in the plasma of the RFI discharge and in the quenching zone of the system. In this work, for the first time, numerical simulation was used to study the kinetics of NO formation in the plasma of the RFI plasma torch and in the quenching zone of the system. Quenching was studied at different rates of cooling in the region of plasma temperature change from 3900 K, which is slightly higher than the optimum (~ 3500 K) for NO generation, to 2000 K, below which the NO dissociation process practically stops. Calculations of the kinetics of NOX formation were carried out using the known codes Bolsig+ and ZDPlascin, taking into account the obtained experimental data.
