Выполнены расчеты экономии топлива для замещения природного газа (NG) влажным технологическим газом (доменным (BFG), коксовым (COG), их смесями) с учетом реальных технологических параметров (на примере конкретного металлургического комбината). Все расчеты произведены в рамках авторской методологии замещения топлив, учитывающей 1-е и 2-е начала термодинамики. При условии сохранения потока полезно использованной полной энтальпии, как основного требования предложенной методологии, и учета соответствующего КПД использования топлива выполнен анализ возможности экономии или возникновения перерасхода NG. Проведен расчет потребного потока теплоты сгорания природного газа в зависимости от содержания влажного доменного газа в смесях NG + BFG для случаев замены NG технологическими газами. Установлено, что наличие влаги в топливоокислительной смеси всегда снижает КПД топочной камеры или энергетического процесса и агрегата. Для повышения КПД высокотемпературной печи (котла) необходимо обеспечить подогрев компонентов горения при утилизации теплоты уходящих продуктов сгорания. Показано, что КПД топливоиспользующей системы может быть существенно повышен при срабатывании потенциала (избыточной полной энтальпии) рабочего тела (продуктов сгорания). Дополнительные преимущества обусловлены тем, что располагаемая теплота продуктов сгорания с влажным воздухом в полном диапазоне температур – от теоретической температуры горения до температуры окружающей среды, – рассматриваемая по условиям равновесия, в том числе с учетом теплоты конденсации, возрастает с увеличением влагосодержания исходных компонентов горения: воздуха-окислителя и/или газового топлива.</p></abstract><trans-abstract xml:lang="en"><p>The influence of hydration of the components of combustion (air-oxidizer and – in some cases – fuel) including hydration in the conditions of substitution of natural gas by alternative gas fuels, viz. by coke blast furnace mixture and natural blast furnace mixture – on energy efficiency of the use of different fuels has been determined. Calculations of fuel saving for substitution of natural gas (NG) by wet process gas (blast furnace gas (BFG), coke gas (CG), their mixtures) were performed taking into account real technological parameters (on the example of a specific metallurgical plant). All the calculations were performed within the framework of the author’s methodology on fuel substitution grounded on the 1st and the 2nd laws of thermodynamics. The analysis of possibility for saving or overspending NG is performed in the conditions of preservation of the flow of the used total enthalpy (as the main requirement of the methodology that had been proposed) and of taking into account the corresponding efficiency of fuel use. The calculation of the required heat flow of natural gas combustion depending on the content of wet blast furnace gas in NG + BFG mixtures for the cases of NG substitution by process gases has been carried out. It is established that the presence of moisture in the fuel-oxidation mixture always reduces the efficiency of the combustion chamber or the energy process and the unit. In order to increase the efficiency of a high-temperature furnace (boiler), it is necessary to provide heating of combustion components when utilizing the heat of the outgoing combustion products. It is shown that the efficiency of the fuel-using system can be significantly increased when the potential (excess total enthalpy) of the working fluid (combustion products) is activated. There are additiоnal benefits due to the fact that the existing heat of products of combustion with humid air in a full range of temperatures – from the theoretical combustion temperature to ambient temperature under conditions of equilibrium, including account of the heat of condensation – increases with increasing moisture content of the initial components of combustion, viz. air-oxidizer and/or fuel gas.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>альтернативное газовое топливо</kwd><kwd>влажный воздух (газ)</kwd><kwd>доменный газ</kwd><kwd>замещение топлив</kwd><kwd>коксовый газ</kwd><kwd>полная энтальпия</kwd><kwd>теоретическая температура горения</kwd><kwd>экономия (перерасход) природного газа</kwd><kwd>термодинамический анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>alternative gas fuel</kwd><kwd>moist air (gas)</kwd><kwd>blast furnace gas</kwd><kwd>fuel substitution</kwd><kwd>coke gas</kwd><kwd>total enthalpy</kwd><kwd>theoretical combustion temperature</kwd><kwd>natural gas saving (overspending)</kwd><kwd>thermodynamic analysis</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">Сорока, Б.
