Вместе с тем она является одним из основных потребителей первичных энергетических ресурсов и оказывает заметное влияние на окружающую среду. Повышение энергетической и экологической эффективности систем подготовки газа и очистки атмосферных выбросов для надежного и экологически безопасного функционирования энергетических систем городов является актуальной проблемой. Проведено теоретическое определение эффективности очистки газового топлива для городских энергоисточников в циклоне-фильтре с использованием относительного числа Рейнольдса Rer , которые были валидированы на данных по серийным циклонам, выпускаемым в настоящее время и широко используемым в РФ. Также на основе методов Computational Fluid Dynamics (CFD) выполнены численные исследования движения потока и экспериментальные исследования характеристик скоростей и давлений в нем. Для описания процесса сепарации использована система из осредненных по Рейнольдсу уравнений Навье-Стокса. Выполнены стендовые испытания циклона-фильтра, конструкция которого была разработана на базе серийного циклона ЦН-11 диаметром 200 мм. Результаты теоретических, численных и экспериментальных исследований показали возможность и целесообразность усовершенствования циклона путем установки в нём тканевого фильтра, что позволяет уменьшить диаметр отсекания (частиц, улавливаемых на 50%) со средних для стандартных циклонов значений 10 мкм до 0,4 мкм, т. е. обеспечивая улавливание мелкодисперсных частиц класса РМ10 , РМ2,5 , при одновременном повышении с минимальными энергозатратами эффективности очистки до 99,89%. Таким образом, циклон-фильтр может быть использован в качестве второй (окончательной) ступени очистки.</p></abstract><trans-abstract xml:lang="en"><p>Energy is a basic industry that affects the state of the entire economy. At the same time, it is one of the main consumers of primary energy resources and has a noticeable impact on the environment. Increasing the energy and environmental efficiency of gas treatment systems and purification of atmospheric emissions for the reliable and environmentally safe operation of urban energy systems is an urgent problem. A theoretical determination of the efficiency of gas fuel purification for urban energy sources in a cyclone filter was carried out using the relative Reynolds number Rer, with the data obtained further validated based on data on serial cyclones currently produced and widely used in the Russian Federation. Besides, on the basis of CFD methods, numerical studies of the flow movement and experimental studies of the characteristics of velocities and pressures in the flow were carried out. A system of Reynolds-averaged Navier-Stokes equations is used to describe the separation process. Bench tests of the cyclone filter were carried out, which was designed on the basis of the serial cyclone TSN-11 with a diameter of 200 mm. The results of theoretical calculations, numerical and experimental studies showed the possibility and expediency of improving the cyclone by installing a fabric filter in it, which makes it possible to reduce the cut-off diameter (for particles captured to 50%) from the average values for standard cyclones (10 μm) to 0.4 μm, i.e. e. provides capturing of fine particles of the PM10, PM2.5 class, while increasing the purification efficiency up to 99.89% with minimal energy consumption. Consequently, the cyclone filter can be used as the second (final) stage of purification.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>энергетическая система</kwd><kwd>циклон</kwd><kwd>фильтр</kwd><kwd>сепарация</kwd><kwd>газоочистка</kwd><kwd>метод моделирования</kwd><kwd>энергозатраты</kwd><kwd>топливообеспечение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>energy system</kwd><kwd>cyclone</kwd><kwd>ﬁlter</kwd><kwd>separation</kwd><kwd>gas puriﬁcation</kwd><kwd>modeling method</kwd><kwd>energy consumption</kwd><kwd>fuel supply</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">Замалиева А.
