Droplet Extinction and Combustibility Ranking Indices of Chlorinated Hydrocarbons

摘要

ABSTRACTThe burning rates as well as the extinction droplet and flame diameters of droplets of n-alkanes and chlorinated alkanes have been experimentally determined as functions of system pressure and ambient oxygen concentration in environments of reduced pressure. By substituting these empirically-determined extinction data into a modified asymptotic theory of droplet extinction, the overall activation energies for the oxidation of these compounds have been determined. Various combustibility ranking indices are proposed based on these overall kinetic constants empirically-determined in diffusive media.
