The existence of a new type of superadiabatic temperature phenomenon in flames and during autoignition due to a competition between chemical reactions is inferred from literature data and the results of mathematical modeling of chemical kinetics and numerical experiments. The mechanisms, conditions for the occurrence, and nature of the phenomenon are discussed. It is noted that this phenomenon may have promising academic and practical applications.
