Abstract
Introduction. The article analyzes the role of thermal and chain combustion in a fire in a closed volume of gas compressor stations. The mechanism of the branched-chain combustion of saturated hydrocarbons in the gas phase has been determined. The analysis of existing models of combustion of saturated hydrocarbons is carried out. Probabilistic model of branched-chain combustion of saturated hydrocarbons in a closed volume of gas compressor stations based on the energy characteristics of the chain carriers in the branched-chain combustion process has been compiled. The purpose of the study is to establish a model of qualitative relationship between the kinetic mechanisms of the branched-chain combustion process of saturated hydrocarbons and the chain carriers involved in it (atoms and radicals) in the closed volume of gas compressor stations. Research methods. To obtain the results the general scientific and special methods of scientific knowledge - the analysis, synthesis, theory of branched-chain combustion process, thermal theory of combustion, theory of energy Boltzmann distribution, were used. The results of the study. The analysis of the main mechanisms of the kinetics of the chemical reaction of combustion in a closed volume of gas compressor stations was carried out. A qualitative model of the relationship between the kinetic mechanisms of the branched-chain combustion process of saturated hydrocarbons and the chain carriers involved in it (atoms and radicals) in the closed volume of gas compressor stations is established. Conclusion. The obtained probabilistic model allows us to calculate the probability of the occurrence of branched-chain combustion of saturated hydrocarbons within the closed volumes of gas compressor stations for different reaction chains. It allows us to choose the most effective control of chemical reactions of combustion under these conditions, that is, to define how to perform volumetric extinguishing most effectively. The found model does not contradict existing models, and the results obtained are confirmed by empirical data.
