The results of experimental studies of heat transfer in the layers of forest fuel (FF) when localizing the propagating fronts of its flame combustion and thermal decomposition using protective water lines are presented. These lines were moistened layers of FF before the thermal decomposition front. The varied parameters were the volume of poured liquid, size of the barrier line, conditions of material wetting, specific consumption, irrigation density, etc. The main attention was focused on defining the conditions of thermal balance at a boundary between the material subjected to thermal decomposition and the protective water line to determine the dominant mechanisms of combustion suppression or localization. The experiments were carried out with typical forest fuels: leaves, needles, and a mixture of leaves and needles. It was established that the effective conditions of combustion localization may be provided by suppressing the material burning in the vicinity of the water line boundary. This important experimental result has become the basis for the development of a physical and mathematical model for predicting the effective conditions of the material combustion localization. The developed model serves to obtain data that justify the determining role of energy sink to the protective water line, as well as the flame combustion and pyrolysis of the material in front of it.
