Abstract
It has been established that, contrary to previous ideas chemical processes in the propagation of flame, explosion and detonation of gases, are chain reactions proceeding according to previously unknown laws of non-isothermal chain processes. The characteristic reaction times in deflagration and detonation in the combustion zone are less than a ten-thousandth and a millionth of a second, respectively. The features of the mechanisms and laws that determine such high rates and accelerations of reactions, their extremely strong temperature dependence is revealed. Using kinetic and spectroscopic methods, the decisive role of atoms and radicals, which are formed in concentrations reaching tens of percent of the concentrations of the initial reagents, is shown. Efficient chemical methods for controlling all combustion modes have been developed.
