Abstract: Research related to the development, implementation, and improvement of hydrogen injection technology in blast furnaces is becoming widespread worldwide, which explains the relevance of the research presented in this article. The article is devoted to analyzing the impact of hydrogen on the technical-economic, thermal, exergy, and exergo-ecological indicators of blast furnace smelting while maintaining the theoretical temperature within a rational range (1800-2300°C) with an agglomerate/pellet ratio of 79%:21% (baseline scenario) and 50%:50% (forecast scenario). The coke replacement factor for hydrogen when using hydrogen in blast furnace smelting has been established. The study was conducted using the example of the best period of operation of a blast furnace in Ukraine operating on pulverized coal fuel. The theoretical hydrogen consumption in a blast furnace was determined in this study based on the Gruner principle. The quantitative values of CO2 emissions, technical and economic, thermal energy, and exergy indicators of blast furnace smelting using hydrogen for two blast furnace operating modes were established – for agglomerate/pellet ratios of 79:21% and 50:50%.
