Установлено, что при замещении воды в составе водоугольного топлива аналогичным по массе (не более 25%) количеством пирогенетической жидкости значение плотности суспензии увеличится на 14% при температуре 293 К. Предварительный нагрев водоугольных суспензий до 363 К позволяет снизить рост значения плотности до 7%. Результаты экспериментов показали, что наибольшее влияние термической подготовки исследовавшихся суспензий на их динамическую вязкость характерно для диапазона температур от 293 до 333 К. При таких значениях температур снижение вязкости суспензии возможно на 17-20%. Предварительный нагрев суспензий перед распылением в диапазоне изменения температур от 293 до 333 К позволяет увеличить угол раскрытия струи на 21-29% в сравнении с двухкомпонентным водоугольным топливом при температуре 293 К. Замещение более 25% по массе воды пирогенетической жидкостью в составе водоугольного топлива нецелесообразно для исследовавшейся марки угля с точки зрения значительного увеличения вязкости. Предварительный нагрев водоугольного топлива перед распылением позволяет снизить значение среднего размера капель на 5-9%.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ.

Efficiency substantiation of thermal preparation of coal-water slurries based on pyrogenetic liquid by the results of experimental studies.</p></sec><sec><title>METHODS</title><p>METHODS. When solving this problem, the Brookfield RVDV-II+Pro rotary viscometer, general-purpose hydrometers, and the Interferometric Particle Imaging method were used.</p></sec><sec><title>RESULTS</title><p>RESULTS. It was found that when water in coal-water fuel is replaced by a similar amount of pyrogenetic liquid (no more than 25%), the density of the slurry increases by 14% at a temperature of 293 K. Preheating of coal-water slurries to 363 K reduces the increase in the density value to 7%. The experimental results showed that the greatest influence of the thermal preparation of the studied slurries on their dynamic viscosity is characteristic of the temperature range from 293 to 333 K. At such temperatures, a decrease in the viscosity of the fuel is possible by 17-20%. Preheating of slurries before spraying in the temperature range from 293 to 333 K makes it possible to increase jet spraying angle by 21-29% in comparison with two-component coal-water fuel at a temperature of 293 K. Substitution of more than 25% by weight of water with pyrogenetic liquid in coal-water fuel is impractical for the studied grade of coal from the point of view of a significant increase in viscosity. Preheating coal-water fuel before spraying reduces the average droplet size by 5-9%.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION. The efficiency of thermal preparation of coal-water slurries based on pyrogenetic liquid by the results of experimental studies of rheological properties and spraying characteristics was substantiated.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>бурый уголь</kwd><kwd>пирогенетическая жидкость</kwd><kwd>водоугольное топливо</kwd><kwd>термическая подготовка</kwd><kwd>вязкость</kwd><kwd>распыление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lignite</kwd><kwd>pyrogenetic liquid</kwd><kwd>coal-water fuel</kwd><kwd>thermal preparation</kwd><kwd>viscosity</kwd><kwd>spraying</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">эксперименты по определению реологических свойств водоугольных топлив проводились при поддержке Министерства науки и высшего образования Российской Федерации (проект №075-00268-20-02 (ID: 0718-2020-0040)), исследования характеристик распыления водоугольных топлив выполнены при финансовой поддержке в соответствии с дополнительным контрактом № 075-03-2021-138/3 о субсидии из федерального бюджета Российской Федерации на финансовую поддержку реализации государственного задания для государственных услуг (внутренний номер 075-GZ/X4141/687/3</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">Садовский Д.Ю., Макаров А.С., Савицкий Д.П., и др.
