Purpose. At the current stage of operation of the defrosting garages of the freight station of the industrial enterprise, the defrosting of wagons with bulk raw materials takes place in conditions of a changing environment, which leads to low efficiency of the interaction of railway transport and the unloading complex. To solve this problem, it is necessary to identify the modes of operation of the defrosting garages of the cargo station of the industrial enterprise in dynamic conditions, to analyze the consumption of natural gas for defrosting. Research methods. The following methods were used during the research: synthesis and analysis for the study of the issue and scientific publications regarding the state and ways of identifying the modes of operation of the defrosting garages of the cargo station of the industrial enterprise; experiment planning - to obtain a multidimensional, diverse array of statistical data; theory of probability and mathematical statistics - for data processing, obtaining correlation dependences of indicators of identification of modes of operation of defrosting garages of a cargo station of an industrial enterprise in dynamic conditions. The results. The work is devoted to the solution of the scientific and technical problem of identifying the operating modes of the defrosting garages of the cargo station of the industrial enterprise in the conditions of a changing environment. The work evaluates the modes of operation of the defrosting garages of the cargo station of the industrial enterprise when defrosting bulk raw materials.The influence of external factors on the consumption of natural gas during defrosting of bulk raw materials in wagons was evaluated. On the basis of research conducted in the process of defrosting bulk raw materials in wagons, two temperature modes of operation of garages were identified, which determine different gas consumption. Basic, regulatory mode with a constant defrosting temperature set by technological standards and maximum gas consumption. Periodic, with reduced gas consumption, is characterized by a decrease in temperature after 6-7 hours and subsequent defrosting using accumulated heat, which ensures a decrease in gas consumption. The possibility and expediency of wide practical use of accumulated heat in the process of defrosting bulk raw materials in wagons has been established. The temperature and time parameters of the process of defrosting bulk raw materials in wagons using accumulated heat are proposed, which ensures a significant reduction in energy consumption. Increasing the efficiency of the defrosting garages of the freight station of the industrial enterprise was achieved on the basis of the development of a method and model of natural gas consumption when defrosting bulk raw materials in wagons using accumulated heat. The scientific novelty consists in the identification of the operating modes of the defrosting garages of the cargo station of the industrial enterprise in the conditions of a changing environment, which is based on a multidimensional, diverse array of experimental data. Practical significance.The presented theoretical provisions regarding the modes of operation of the defrosting garages of the freight station of the industrial enterprise made it possible to develop a method and model of natural gas consumption during defrosting of bulk raw materials in wagons using accumulated heat.
