Abstract: The results obtained in the work confirm the possibility of using fire extinguishing aerosols based on inorganic potassium salts for the sublayer extinguishing of alcohols in tanks. In comparison with the classical methods of extinguishing, this method provides more efficient and reliable extinguishing of the flame, because the aerosol is supplied under the layer from the liquid in the tank, which ensures complete penetration of the aerosol into the combustion zone, extinguishing purity and high extinguishing rate2019-01-01T00:00:00ZPROSPECTS AEROSOL SUBLAYER QUENCHING OF ALCOHOLSБаланюк, Володимир МірчовичКозяр, Назарій МихайловичКравченко, Антон Вікторовичhttps://sci.ldubgd.edu.ua/jspui/handle/123456789/107462021-06-29T10:50:36Z2019-12-01T00:00:00ZTitle: PROSPECTS AEROSOL SUBLAYER QUENCHING OF ALCOHOLS

Abstract: The study addresses the problems of gas alcohols and describes the factors that make the fire extinguishing efficiency of aerosol refractory gas alcohol. To date, alcohol storage facilities are not sufficiently protected, as evidenced by the fires that occur on them. The actuality of the work is emphasized by the fact that the fires at the objects for the storage and processing of alcohols and their mixtures are characterized by a high velocity of flame propagation up to 10 m/s, and the achievement of high values of temperatures inside the volume in the first minutes, the possibility of explosions of both gas and air mixtures and pressure vessels subjected to heat. The article theoretically describes the quenching process and shows that such quenching must be effective at the expense of synergies between the factors of influence. The paper presents the analysis and theoretical generalizations of the process of extinguishing alcohols and alcohol-containing liquids. The disadvantages of quenching alcohols and alcohol-containing liquids by foam agents are indicated. The process of quenching by inert gas is considered and the method of sublayer quenching of alcohols by extinguishing aerosol is proposed. It is established that sublayer quenching by aerosol occurs in 3 stages. At the first stage-at the exit of the aerosol there will be mixing of the liquid, reducing the surface temperature of the combustible liquid and equalizing the temperature on its height the column of the liquid. At the second stage-after the aerosol exits the fluid layer and enters the surface, the concentrations of the components of the combustion mixture are reduced, the radiation shielded …2019-12-01T00:00:00Z
