The thermodynamic theory of combustion in an enclosure was applied to analyse the process of explosion of hexane vapour or hexane droplets - air mixtures in the chambers of different volumes. The relations between thermodynamic parameters and fuel consumption were determined. These relations and the overpressure histories taken from Ref.[1] were used to estimate the combustion rate and the final degree of hexane burned. Modified B.A. Khasainov's law of combustion of particles was applied to describe the process of combustion hexane droplets in air. The parameters of this equation were estimated.
