The purpose of this work is to characterize the combustion of little samples of some well‐known polymeric materials, polyethylene, polypropylene, and polystyrene, in an atmosphere of quiescent hot air at different temperatures. The analytical treatment of this problem, which is a heat and mass transfer one with chemical reaction between pyrolysis and oxidizer gases, is based upon the fact that the burning regime is diffusion controlled. A mathematical approach developed from Spalding's theory, taking into account radiative effects, is applied to this model of combustion. Experimental results allow us to determine the apparent heat of combustion of these different materials and to study the evolution of radiative and convective fluxes.
