THERMOPHYSICAL AND THERMOKINETIC CHARACTERISTICS OF FOREST COMBUSTIBLE MATERIALS

Experiments on determination of main thermophysical parameters (heat conductivity, heat capacity, thermal diffusivity) and thermokinetic characteristics (activation energy of pyrolysis and fl aming) of typical forest combustible materials and their mixtures, taken from the Siberian, Central, Southern, and Far Eastern Federal Districts of Russia, have been performed in the wide temperature range 298–423 K corresponding to the initiation of thermal decomposition and subsequent fl aming of forest combustible materials. Results of these experiments were compared with experimental data obtained by other researchers. A database, which can be used in the mathematical simulation of the thermal decomposition and fl aming of forest combustible materials as well as in the determination of conditions necessary for the localization and suppression of a forest fi re, has been developed.
