The main factors influencing the occurrence and spread of grassland fires have been analyzed, and an installation has been designed to create conditions for the propagation of flame along sloping grass cover. Experimental studies have been carried out to determine the parameters and methods of applying foam barrier strips, laid using working solutions of a foaming agent, provides the generation of foam with increased stability for extinguishing ground fires in ecosystems with grass cover. It was found that the minimum width of such a protective strip depends on weather conditions (wind speed, humidity, ambient temperature), relief, flame height. It was determined that the ratio of the width of the barrier strip to the height of the grass cover should be 3: 1 on the plain in almost calm weather. The height of the foam layer should be at least 0.2 m, and the width has a significant influence. In the presence of wind and a slope of the relief, the width of the strip should grow proportionally according to the dependence. An improved design of a special fire barrel is presented by the creation of a screw section and an increase in productivity to 13.24 - 15.98 l / s and an increase in the irrigation radius for pressures of 0.4 - 0.7 MPa and recommendations for its use with the simultaneous use of surfactants are developed. for extinguishing peat inclusions during ground fires in ecosystems. It has been determined that potash (K2CO3) does not affect the thermal conditions of spontaneous combustion of peat in terms of concentration in an aqueous solution from 5% to 20%. An aqueous solution of ammophos with inclusions (NH4H2PO4 + (NH4) 2HPO4) at a concentration of 5% in them also does not affect, however, the addition of an aqueous solution of Bars S-2 foaming agent in an amount of 0.5% reduces the ability of peat to ignite spontaneously.  Product Description popup.authors Kyryliv Yaroslav Bogdanovych Mnykh Maryana-Mariya Romanivna Sukach Roman Yuriyovych popup.nrat_date 2021-09-06 Close
