On the Anniversary of the Phenomenon of "Solid Flame" about Some Features of Modern Practice of the Theoretical Description of Combustion Processes

This paper is devoted to a review of the widespread practice of the combustion processes description using the so-called classical combustion theory equations without proper clarification of the real kinetics mechanisms of physical processes under consideration. The «vitality» of this type theoretical description is related to the mathematical properties of the functions used. Below some various examples and historical facts, illustrating the idea, are presented, in particular, connected with emergence and development of the "solid flame" science or SHS (Self propagating High temperature Synthesis), being partially a result of a large policy, associated with the collapse of the USSR.
