Simulation of extinguishment fires in a gas compressor station engine room with temperature-activated water

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.
