The results of non‐equilibrium heating of air, carbon dioxide, nitrogen in a plasmatron with porous arc channel at intense gas blow are presented. The investigations are performed in the current range 100–500 A, at the gas pressure being higher than atmospheric. The deviation from the equilibrium conditions in the flow behind the plasmatron for air and carbon dioxide is evaluated by reaction products of nitrogen oxides synthesis and carbon dioxide conversion outputs. It is shown that these processes have non‐equilibrium mode and it can explained by an increased products output. For nitrogen the excess of the vibrational temperature T v over the translational T is defined by the laser probe method (at T = 1500 K T v = 3000 K).
