В существующих горелках, применяемых на ДСП, газ и кислород подаются раздельно через газокислородные и рафинирующие горелки, что обеспечивает диффузионный режим горения. Диффузионный режим в условиях использования в рабочем объеме ДСП имеет ряд недостатков, таких как неоптимальное распределение температурных и концентрационных полей продуктов сгорания, повышенный угар железосодержащих компонентов шихты. В данной работе представлены результаты расчетного исследования физико-хими­ческих свойств продуктов сгорания по длине факела для горелок фирм VAI FUCHS, SMS DEMAG и НТПФ «Эталон» при концентрации кислорода в окислителе 95 мас. %.  Были проанализированы результаты компьютерного моделирования температурных полей факелов с целью оценки риска «проскока» пламени во внутренний объем горелки. Авторы провели сравнительное исследование характеристик факелов в горелочных устройствах с диффузионным и кинетическим режимами горения. На основании полученных данных предложен переход от диффузионного режима сжигания природного газа к кинетическому, что может повысить энергоэффективность использования горелок, равномерность температурных и концентрационных полей продуктов сгорания, а также снизить угар железосодержащей шихты. Исследование производилось с помощью компьютерного моделирования в пакете программ ANSYS в модуле CFX. Полученные результаты могут быть полезны для оптимизации тепловых процессов в рабочем объеме ДСП, снижения расхода электроэнергии и предотвращения аварийных режимов эксплуатации горелок.</p></abstract><trans-abstract xml:lang="en"><p>In modern electric arc furnaces (EAF), charge heating by natural gas (NG) combustion products with process oxygen is widely used to reduce the power consumption and intensify the thermal performance. In existing EAF burners, gas and oxygen are supplied separately through oxygen gas and refining burners, which ensures the diffusion combustion mode. The diffusion mode in conditions of EAF working space has a number of disadvantages, such as non-optimal distribution of temperature and concentration fields of combustion products, increased burn-off of iron-containing components of the charge. This paper presents the results of a computational study of the physico-chemical properties of combustion products along the torch length for the burners of VAI FUCHS, SMS DEMAG and NTPF Etalon Ltd. companies at oxygen concentration in the oxidizer of 95 wt. %. The results of computer modeling of temperature fields in the torches were analyzed in order to assess the risk of flame “slip” into the burner internal volume. The authors carried out a comparative study of the characteristics of torches in the burner devices with diffusion and kinetic combustion modes. Based on the data obtained, a transition from the diffusion mode of natural gas combustion to the kinetic mode is proposed, which can increase the energy efficiency of using burners, uniformity of temperature and concentration fields of combustion products, and reduce carbon monoxide of the iron-containing charge. The study was performed using computer modeling in ANSYS software package in CFX module. The obtained results can be useful for optimizing thermal processes in EAF working space, reducing power consumption and preventing emergency operation of burners.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дуговая сталеплавильная печь</kwd><kwd>горелка</kwd><kwd>природный газ</kwd><kwd>кислород</kwd><kwd>факел</kwd><kwd>концентрация</kwd><kwd>температурное поле</kwd><kwd>режим</kwd><kwd>диффузионный</kwd><kwd>кинетический</kwd></kwd-group><kwd-group xml:lang="en"><kwd>EAF</kwd><kwd>burner</kwd><kwd>natural gas</kwd><kwd>oxygen</kwd><kwd>torch</kwd><kwd>concentration</kwd><kwd>temperature field</kwd><kwd>mode</kwd><kwd>diffusion</kwd><kwd>kinetic</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">Белковский А.Г., Кац Я.Л., Краснянский М.В.
