The physical concepts and the results of the thermal theory of combustion are used as a basis for the qualitative analysis and mathematical simulation of transformation of stationary temperature distributions along the length of an adiabatic reactor in the case of periodic perturbations of the velocity of the reagent in the reactor and its temperature at the entrance of the reactor. It is established that, with certain values of the amplitude and frequency of harmonic perturbations of the velocity of the reagent, it is possible to improve the thermal stability of the process (increase the pre-explosion heating).
