STUDY OF THE TACTICAL AND TECHNICAL CHARACTERISTICS OF A SPECIAL FIRE BARREL FOR EXTINGUISHING UNDERGROUND FIRES IN PEAT-FOREST ECOSYSTEMS ; ДОСЛІДЖЕННЯ ТАКТИКО-ТЕХНІЧНИХ ХАРАКТЕРИСТИК СПЕЦІАЛЬНОГО ПОЖЕЖНОГО СТВОЛА ДЛЯ ГАСІННЯ ПІДЗЕМНИХ ПОЖЕЖ В ЕКОСИСТЕМАХ ТОРФ-ЛІС
One of the promising methods of extinguishing fire is to extinguish with water or solutions of extinguishing agents. This method is relevant for extinguishing underground fires in peat-forest ecosystems, in particular litter and peat. For this, a special fire barrel was developed to extinguish underground fires using water extinguishing agents with the addition of surfactants. In the work, the tactical and technical characteristics of a special fire barrel for extinguishing underground fires are established and a method for extinguishing them with fire extinguishing agents using surfactants is developed.A special fire barrel equipped with auger blades has been developed, which perform a number of functions: cut solid inclusions when deepening, the trunk, hold the trunk in peat layers, open free channels to withdraw excess water to the surface without erosion of the soil.Based on the studies, it is possible to select the optimal parameters of pressure and fluid flow for specific conditions of quenching of peat and litter in the peat-forest ecosystem. In addition, it should be noted that the developed special fire barrelFire Safety, №36, 2020 109 has a more than 3 times greater consumption of extinguishing agent than existing analogues, such as TS-1, TS-2, SPT-70. This suggests that in practice such trunks will be needed less, and their extinguishing efficiency will be higher. As a fire extinguishing agent, it is recommended to use not water, but aqueous solutions of Bars S-1, Bars S-1m blowing agents containing surfactants that reduce the surface tension of water and increase the wetting ability of bedding, peat and are one of the most effective ways to combat peat fires.The fluid flow rate of a special fire barrel for extinguishing underground fires in peat-forest ecosystems was determined at pressures of 0.4 and 0.7 MPa, which are respectively 13.24 and 15.98 l/s.The fluid flow rate was calculated at 0.5 and 0.6 MPa, which is 14.26 and 15.40 l/s, respectively.Based on experimental and calculated data, it was ...
