Abstract: The aim of this work is to identify the parameters influencing the flame behavior. Three different species (Pinus pinaster, Pinus halepensis and Erica arborea) involved in forest fire were crushed to decrease the geometric effects on their combustion. The flaming behavior is studied experimentally from unsteady, axisymmetric, non-premixed laminar flames. The distribution of temperature, the flame geometry, the mass loss as well as the gases released by the fuels are measured. This study confirms the role of the mass burning rate of fuels on the flame dynamics. However, this work highlights a second influence for laminar flames: the composition of degradation gases. It affects the flame geometry and changes the combustion kinetics in the reaction zone.
