The last, apparently, is one of stronger preheating sources in thereaction zone. Thus, in this case the system got more energy for an initiating of following heatabsorption stage, being be trigger of all possible endothermic processes. Then, the graduallyweakening brunched oxygen cycle competes with equally hardening oxygen-free one, and thesecond rising stage begins. Judging by the reactions which contribute to heat release on thisstage, the H atoms and СН 3 radicals, released from the peroxide form, play a leading part init, while the role of oxidizer comes to water. Thus, if one will be extended at now theresponsible variant of model by observable number of reactions of these active agents andtheir interactions product, then it has be reached a good level of the description of the mixedchain-heat process of combustion oneself. The kinetic features of the system are analyzedresponsible for the influence of different factors on the process regimes.The work is supported under project No.6025 on the RAS Presidium Program ofphysical-chemical investigations «New Approaches to the Fuels Chemistry and PowerEngineering».References1.
