Abstract : The method of activation energy asymptotics is used to describe the entire history of a carbon particle suddenly immersed in a hot oxidizing ambient. Under appropriate conditions which are established by the analysis, the history of the particle is shown to consist principally of a heat-up period during which no significant chemical reaction takes place followed by a period involving diffusion-limited mass loss and terminating in complete particle consumption. Between these two extended periods brief ignition and post-ignition periods are described. The final demise of the particle occurs in a complex extinction period during which all the quantities describing the particle behavior undergo large variations. (Author)
