Title: Study of Efficiency Parameters for Using Fire-Extinguishing Aerosols to Suppress Flammable Liquid Fires in Open Spaces Authors: Balanyuk, Volodymyr Abstract: In production and economic activities, a large number of flammable and flammable liquids are used. A significant part of them is stored and circulated in industrial equipment located in open spaces. This creates a risk of fires at petrol stations, energy companies, tank farms and other facilities, especially in wartime, when rapid response by firefighters is difficult. Automated fire extinguishing systems using fire extinguishing aerosols are a promising solution for such situations due to their efficiency, simplicity and reliability.The aim of the study is to determine the optimal conditions and parameters for the use of fire extinguishing aerosols for extinguishing fires of combustible liquids in an open space.To achieve this goal, experimental studies were carried out using a 55B model fire and a fire extinguishing aerosol generator (FAG). The studies included determination of the extinguishing time, aerosol supply intensity, aerosol concentration in the cloud, aerosol supply duration, aerosol cloud retention time and aerosol coverage area.According to the study, it was found that successful extinguishing of the model fire is achieved by supplying aerosol from FAG with a charge of 2800-2880 g from a height of 4.5 metres at a right angle. The following parameters were determined: the optimum aerosol supply rate (160 g/s) and the aerosol concentration in the stream (140-180 g/m3). The duration of aerosol supply is 18-20 seconds, the retention time of the aerosol cloud is 50-60 seconds, and the final aerosol concentration in the cloud is 97 g/m3.The study also analysed the dynamics of changes in the aerosol coverage area and aerosol concentration in different zones of the flow cone. It is shown that the aerosol concentration in all zones of the cone exceeds the required extinguishing concentration.A methodology for determining the parameters of effective use of aerosol fire extinguishing systems in open spaces has been developed.From the analysis, it can be concluded that fire extinguishing aerosols are an effective means of extinguishing fires of flammable liquids in open spaces. The results obtained can be used for the design and implementation of automated fire extinguishing systems at facilities with increased fire hazard, which in turn will increase the efficiency of fire extinguishing, help reduce material damage and risk to human life, especially in wartime.

Title: FACTORS INFLUENCING THE BURNING RATE OF COMPOUNDS FROM WHICH FIRE EXTINGUISHING AEROSOLS ARE FORMED Authors: Balanyuk, Volodymyr Abstract: FACTORS INFLUENCING THE BURNING RATE OF COMPOUNDS FROM WHICH FIRE EXTINGUISHING AEROSOLS ARE FORMED The article deals with the topical issue of the influence of various factors on the combustion rate of fire extinguishing aerosol compounds (AFC). Aerosol fire extinguishing agents are becoming increasingly popular due to their efficiency, low fire extinguishing concentrations and environmental safety. However, for their effective use, it is necessary to understand and control the factors that affect the burning rate of AFC and the formation of fire extinguishing aerosol. To identify and analyse the factors affecting the burning rate of AUS in order to optimise their composition and increase the efficiency of fire extinguishing. The method of scientific analysis and synthesis, as well as the experimental method of research were used in the work. The main factors influencing the burning rate of AFC were determined. The chemical composition and ratio of the components of the AFC (fuel, oxidant, catalysts, additives). Geometric parameters of the AFC charge (presence of channels, holes). Physical properties of the components (melting point, molecular weight). The presence of internally bound oxygen in the molecular structure of the fuel. It has been established that to increase the combustion rate of AFC, it is necessary to use thermally unstable combustibles (rubbers, iditol, sucrose, epoxy resin), the optimal ratio of oxidants (potassium nitrate, potassium chlorate, potassium perchlorate) and catalytic additives. It is shown that ensuring the maximum combustion area of the AFC and the use of a complex geometric charge design contribute to an increase in the rate of fire extinguishing aerosol formation. The combustion rate of AFC is a key factor determining the effectiveness of fire extinguishing. To achieve a high combustion rate, it is necessary to optimise the composition of the AFC, taking into account the chemical and physical properties of the components, as well as the geometric parameters of the charge. Further research should be aimed at a detailed study of the influence of each of the factors on the burning rate of the AFC and the development of new effective compositions of aerosol-forming compounds.
