Газоперерабатывающая промышленность является довольно энергоемкой и требует значительных затрат энергии для осуществления своей деятельности. Поиск путей повышения энергоэффективности предприятий этой отрасли является необходимой и актуальной задачей.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ. Определение возможностей повышения энергоэффективности работы действующих промышленных печей газоперерабатывающего предприятия с разработкой энергосберегающих мероприятий.</p></sec><sec><title>МЕТОДЫ</title><p>МЕТОДЫ. Для реализации поставленной цели проведено исследование действующих промышленных печей газоперерабатывающего предприятия на предмет возможности полезного использования низкопотенциального тепла уходящих дымовых газов. Проведено технико-экономическое обоснование предлагаемых энергосберегающих мероприятий.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. Анализ предприятия выявил низкий коэффициент полезного действия технологических печей. Причинами низкого КПД является завышенный коэффициент избытка воздуха и высокая температура уходящих дымовых газов. Предложены следующие направления повышения эффективности печей: утилизация тепловой энергии дымовых газов и поддержание коэффициента избытка воздуха на нормативном уровне.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ. Рассчитанный потенциал энергосбережения при снижении температуры уходящих дымовых газов до 160 °C составил 82348,8 Гкал, а при снижении коэффициента избытка воздуха до нормативных 5 % - 8986 Гкал. В сумме эта величина составит около 23% от общей выработки тепловой энергии промышленными печами. Предложенные энергосберегающие мероприятия позволят осуществить утилизацию тепловой энергии дымовых газов и снизить коэффициент избытка воздуха для достижения нормативного соотношения топливо/воздух. Эффект от предложенных мероприятий составит 79694 Гкал, что равно около 20% от общей выработки тепловой энергии промышленными печами.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>THE RELEVANCE</title><p>THE RELEVANCE. The gas processing industry is quite energy intensive and requires significant energy costs to carry out its activities. Finding ways to improve the energy efficiency of enterprises in this industry is a necessary and urgent task. THE PURPOSE. Identification of opportunities to improve the energy efficiency of the operation of existing industrial furnaces of a gas processing enterprise with the development of energy-saving measures.</p></sec><sec><title>METHODS</title><p>METHODS. To achieve this goal, a study of existing industrial furnaces of a gas processing enterprise was conducted for the possibility of useful use of low-potential heat of outgoing flue gases. A feasibility study of the proposed energy-saving measures has been carried out.</p></sec><sec><title>RESULTS</title><p>RESULTS. The analysis of the enterprise revealed a low efficiency of technological furnaces. The reasons for the low efficiency are the overestimated excess air coefficient and the high temperature of the exhaust flue gases. The following directions for improving the efficiency of furnaces are proposed: utilization of the thermal energy of flue gases and maintenance of the excess air coefficient at the regulatory level.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION. The calculated energy saving potential with a decrease in the temperature of outgoing flue gases to 160 ° C was 82348.8 Gcal, and with a decrease in the excess air coefficient to the standard 5% - 8986 Gcal. In total, this amount will amount to about 23% of the total heat generation by industrial furnaces. The proposed energy-saving measures will make it possible to utilize the thermal energy of flue gases and reduce the excess air coefficient in order to achieve a standard fuel/air ratio. The effect of the proposed measures will amount to 79694 Gcal, which is about 20% of the total heat generation by industrial furnaces.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>промышленные печи</kwd><kwd>эффективность</kwd><kwd>энергосбережение</kwd><kwd>дымовые газы</kwd><kwd>утилизация тепловой энергии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>industrial furnaces</kwd><kwd>efficiency</kwd><kwd>energy saving</kwd><kwd>flue gases</kwd><kwd>heat energy utilization</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Министерства науки и высшего образования Российской Федерации в рамках государственного задания № 075-03-2024-226 от 15.02.2024 года.</funding-statement><funding-statement xml:lang="en">This research was funded by the Ministry of Science and Higher Education of the Russian Federation within the framework of the state assignment No. 075-03-2024-226 from 15.02.2024.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">A.
