Kinetics of ′blue' flames in the gas-phase oxidation and combustion of hydrocarbons and their derivatives

Experimental and calculated data on the kinetics of ′blue' flame observed in the gas-phase oxidation and combustion of hydrocarbons and their derivatives are considered. It is shown that blue flames arise due to the decomposition of hydrogen peroxide that forms in the oxidation of hydrocarbons. They manifest themselves by light emission, are identified by partial heat release (the appearance of a step in the time dependences of temperature and pressure observed in closed-vessel experiments) and propagate as conventional hot flames.
