    Abstract:

    This paper considers the possibility of using and improving the mathematical model of heat exchange of the blast furnace process, taking into account the injection of synthesis gas (with different amounts of hydrogen in it) [1-3]. The analysis of existing models of heat exchange of a blast furnace is carried out and arguments are given justifying the need to take into account the characteristics of synthesis gas in the model. In a blast furnace, additional hydrogen in synthesis gas can be used as a partial replacement for coke, which will reduce the amount of carbon dioxide emissions into the atmosphere and increase the energy efficiency of the process. The use of synthesis gas in a blast furnace has a number of advantages and disadvantages. However, when analyzing the current environmental situation, it should be noted that the technology of using synthesis gas has great prospects. Calculations based on the improved model showed a more accurate assessment of the heat transfer characteristics in the blast furnace process when using synthesis gas. The results of the study can be used to effectively optimize the parameters of technological processes in blast furnace production.
