Purpose. Theoretical studies stated that one of the ways to increase the extinguishing efficiency of temperature-activated water (TAW) is the introduction of water-soluble inhibitory compounds into it. However, simulation of total flooding of confined volumes fires by this medium and field experiments confirming the theoretical conclusions were not carried out. The aim of the work was the experimental study of total flooding of fires in gas compressor stations engine rooms with the introduction of inhibitory salts. To realize it, the following tasks were solved: 1) analysis of existing models of total flooding of fires and the formation of a TAW model in the PyroSim hardware and software complex; 2) carrying out mathematical simulation of total flooding of fires with TAW. Methods. Methods of analysis and synthesis were used to evaluate the available data. To study total flooding processes, the theory of branched-chain combustion processes was used. The objectivity of the found theoretical dependencies was confirmed by the experimental method. Findings. The experimental study allowed us to confirm the objectivity of the theoretical dependencies found. The most effective distribution of the polydisperse droplet phase of TAW was determined to create inhibitory properties. Temperature reduction dependences in a confined volume on the quenching time were determined. Research application field. The obtained models can be used to increase the efficiency of suppressing flame combustion in a confined volume. Conclusions. The obtained results will form the theoretical basis for describing the mechanisms of total flooding with TAW.

Purpose. Increasing production of liquefied natural gas (LNG) in the Russian Federation raise the risk of the accidental LNG releases. To prevent the negative consequences of a possible gas-air cloud explosion during LNG release, it is necessary to predict probable emergency scenarios. Regulatory documents for determining fire risk make it possible to define the likely consequences of an explosion of liquefied hydrocarbon gases (LPG) vapor clouds, however the application of calculation methods for LNG requires additional analysis. Methods. The analysis of methods for calculating the parameters of a gas-air cloud explosion in an open space is carried out, the consequences of real gas-air clouds explosions during the emergency LNG release are analyzed. Findings. The analysis of the methods has showed the main uncertainties in predicting the parameters of LNG vapor cloud explosion. Propagation features of LNG vapor cloud, the influence of various gases that are part of LNG are not taken into account. Research application field. The results obtained will allow improving the method for calculating the pressure of the gas-air clouds explosion during the emergency LNG release. Conclusions. The analysis of the real accident with LNG release has showed that the calculated pressures obtained on the basis of the methods are incomparable with the explosion consequences. The further direction for improving the methodology of calculating the explosion pressure of gas-air clouds during the emergency LNG release is determined. To improve the methodology it is necessary to determine the effect of combustible gases, which are part of LNG, on the parameters of the explosion, and also take into account the effect of low temperatures of LNG vapor cloud.

Purpose. The analysis of normative documents regulating the amount of foam supply intensity for extinguishing high-octane gasoline was carried out in the research. The developed technique of determining foam supply critical intensity by various methods depending on the initial heating of high-octane gasoline is described, as well as the experimental installation that allows implementing a combined foam discharge method whereby foam is simultaneously discharged both onto the surface of the combustible liquid and under the layer. Methods. The authors analyzed normative documents regulating fire extinguishment of oil and petrochemicals. The study was carried out at the experimental installation developed according to the appropriate test method. Findings. The analysis of normative documents indicated differences in the criteria for choosing foam discharge intensity for high-octane gasoline. It was decided to determine the possibility of applying increasing factors for standard values of foam discharge intensity depending on time of free fire development in a high-octane gasoline tank. The experimental installation was based on the standardized installation according to GOST R 50588, which was modernized for possible foam discharge in a combined way. Fuel is preheated to determine the heating temperature effect on foam application rate. Model foam generators with a flow rate of 1.8-2.2 g/s and pans of various diameters were used to change the intensity of foam discharge. Research application field. This technique will be used for obtaining data on determining the most effective method of extinguishing high-octane gasoline at different time intervals. The experimental installation will allow obtaining new data on choosing intensity and methods of foam discharge for modern mixed gasolines. Conclusions. The carried-out work showed the relevance of conducted research work aimed at assessing the value of foam discharge critical intensity applying various methods depending on the initial heating temperature of high-octane gasoline in the tank. To determine the target value, the experimental stand and the corresponding test procedure have been developed, the results of which will be given in further publications.
