Abstract
The article presents the results of experimental studies of heat transfer in the layers of forest fuel (FF) at localizing the propagating fronts of its flame combustion and thermal decomposition using protective water lines. Such lines were moistened layers of forest fuel before the front of thermal decomposition. The varied parameters were the volume of poured liquid, the size of the barrier line, the conditions of material wetting, specific consumption, irrigation density, etc. The experiments were carried out with typical forest fuels: leaves, needles, and a mixture of leaves and needles. It has been experimentally established that effective conditions of combustion localization may be provided at suppressing the material burning in the vicinity of the water line boundary. The article presents the results of the analysis of the influence of the velocity of the side airflow on the values of the irrigation density required to prevent the combustion front propagation, with and without the use of an earth layer.
