The role played by the branched-chain mechanism in combustion and explosion at atmospheric and higher pressures

The special features of branched-chain processes were analyzed to show that , in contrast to views commonly accepted until recently, competition betwee n chain branching and termination plays the determining role in combustion and explosion of hydrogen-containing and many other compounds not only at p ressures tens and hundreds times lower than atmospheric but also at atmosph eric and higher pressures. This point opens new horizons in developing the chain process theory and governing the combustion processes. Data illustrat ing the existence of two chain combustion modes are presented.
