FLOW RATE OF WATER TO EXTINGUISH THE EDGE OF THE CREEPING FOREST FIRES

To study the intensity of the water supply for extinguishing of the creeping forest fires edge there were used combustion characteristics (density of heat, heat flow, average rate of burning of forest wood in thickness, while staying combustible forest materials and residues at the fires edge, unburned carbon ratio: mechanical and chemical) on experimental plots in pine, larch forest, on wild slash areas subject to certain provisions of the Guidelines on the characterization of automatic extinguishing water mist. Graphically it was shown the relationship flame height and width of fires edge on experimental plots in the pine and larch forests and on wild slash areas. Analytically it was calculated standard intensity of the water supply for extinguishing of a forest fires edge, taking into account features of the use or storage of flammable materials, or products in specific circumstances, as well as the critical intensity of the water supply for extinguishing. There are calculated values of the regulatory intensity of water supply for extinguishing of creeping forest fires edge tabulated. All of the above leads to the conclusion that the flame height can serve as an indicator to determine the value of regulatory intensity of the water supply for extinguishing of creeping fire. But in our opinion, to calculate the forces, resources and costs it was required to continue the study of firefighting water flow for specific jobs for fighting forest fires. The study will be continued to clarify the costing of water for extinguishing of the creeping fires edge. By design, the calculation should be absolute or equity indices.
