Выполнены расчеты эффективности использования природного газа и пылеугольного топлива в условиях доменного цеха Енакиевского металлургического завода. Подтверждена высокая экономическая эффективность использования природного газа и пыле- угольного топлива в технологических условиях доменного цеха. Увеличение расхода природного газа от базового уровня (71,8 м3/т чугуна) до 110 м3/т чугуна обеспечивает соответственное повышение производительности доменной печи до 107,6 % и снижение расхода кокса до 417,3 кг/т чугуна (–38,4 кг/т чугуна, –8,42 %). Замена природного газа пылеугольным топливом в количестве 160 кг/т чугуна позволила полностью вывести его из состава дутья. При этом расход кокса снизился до 354,59 кг/т чугуна (–101,1 кг/т чугуна; –22,18 %). Повышение расхода пылеугольного топлива до 200 кг/т чугуна с компенсацией температурой дутья 1200 °С и кислородом дутья 25 % обеспечивает повышение производительности доменной печи до 105,8 % и снижение расхода кокса до 303,8 кг/т чугуна (–151,9 кг/т чугуна, –33,33 %). Высокая эффективность применения пылеугольного топлива в условиях Енакиевского металлургического завода объясняется меньшей его стоимостью по сравнению с природным газом, высоким содержанием углерода в угле и значительно меньшим влиянием на теоретическую температуру горения и другие технологические показатели.</p></abstract><trans-abstract xml:lang="en"><p>The method for calculating indicators of blast furnace smelting with replacement of part of coke with additional fuels has been developed on the basis of full and complex compensation and compensating measures. Eﬃciency of the use of natural gas and pulverized coal in the blast furnace conditions of the Enakievo Metallurgical Plant was calculated and it has been confirmed as rather high. Increase in the consumption of natural gas from the baseline (71.8 m3/t of iron) to 110 m3/t ensures a corresponding increase in productivity of the blast furnace to 107.6 % and a decrease in the consumption of coke to 417.3 kg/t of iron (–38.4 kg/t, –8.42 %). Replacing natural gas with pulverized coal in the amount of 160 kg/t of iron made it possible to completely remove it from the blast. At the same time, coke consumption decreased to 354.59 kg/t of iron (–101.1 kg/t; –22.18 %). Increasing the consumption of pulverized coal fuel up to 200 kg/t of iron with compensation of the blast temperature of1200 °Cand oxygen of the blast of 25 % provides an increase in the productivity of the blast furnace to 105.8 % and reduction of coke consumption to 303.8 kg/t of iron (–151.9 kg/t, –33.33 %). High efficiency of the use of pulverized coal in conditions of the Enakievo Metallurgical Plant is explained by its lower cost compared to natural gas, high carbon content in coal and a significantly lower eﬀecton the theoretical combustion temperature and other technological parameters.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>природный газ</kwd><kwd>пылеугольное топливо</kwd><kwd>кокс</kwd><kwd>дутье</kwd><kwd>кислород</kwd><kwd>чугун</kwd><kwd>производительность</kwd><kwd>доменная печь</kwd></kwd-group><kwd-group xml:lang="en"><kwd>natural gas</kwd><kwd>pulverized coal</kwd><kwd>coke</kwd><kwd>blast</kwd><kwd>oxygen</kwd><kwd>iron</kwd><kwd>capacity</kwd><kwd>blast furnace</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Курунов И.Ф.
