Abstract
The paper defines the optimal conditions and characteristics of spraying fire extinguishing compositions to reduce the temperature in the combustion zone of typical combustible forest materials. A series of experiments was carried out to establish the conditions and characteristics of the processes occurring during localization and elimination of combustion of typical combustible forest materials (wood, mixed forest combustible materials) under conditions of exposure of different dispersion water drops. The times of thermal decomposition of solid combustible materials after suppression of fiery combustion by fire extinguishing compositions based on water with the addition of a foaming agent and FR-Les 01 were determined. The minimum volume and spraying mode (droplet sizes) of aerosols of different concentrations were established to effectively reduce the temperature in the combustion zone.
