Переход от углеводородного топлива к водородному позволит практически полностью предотвратить образование углекислого газа в камерах сгорания газотурбинных установок с одновременным увеличением влагосодержания в продуктах сгорания, что делает перспективным утилизацию низкопотенциальной теплоты водяных паров из среды уходящих газов в конденсационных котлах-утилизаторах. В настоящей работе представлены результаты комплексного анализа парогазовых энергоблоков, работающих на водороде и метано-водородных смесях, с дополнительной утилизацией низкопотенциальной теплоты влажных продуктов сгорания в органических циклах Ренкина. Определён уровень энергетической эффективности установок, усовершенствована методика RANS моделирования теплопередачи в конденсационных котлах-утилизаторах, а также оценены габариты теплоутилизирующей установки.</p></abstract><trans-abstract xml:lang="en"><p>Reducing greenhouse-gas emissions in the production of heat and electricity is one of the key avenues of sustainable development. Transitioning from hydrocarbon fuels to hydrogen will virtually eliminate carbon-dioxide formation in the combustion chambers of gas-turbine units while simultaneously increasing the water-vapor content in the combustion products, which makes recovery of the low-grade heat of water vapor from the flue-gas stream in condensing heat-recovery boilers promising. This study presents the results of a comprehensive analysis of combined-cycle power blocks operating on hydrogen and methane–hydrogen mixtures, with additional recovery of the low-grade heat of wet combustion products in Organic Rankine Cycles. The energy-efficiency level of the units is determined, a RANS-based methodology for modeling heat transfer in condensing heat-recovery steam generators is refined, and the overall dimensions of the heat-recovery system are assessed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>водород</kwd><kwd>метано-водородная смесь</kwd><kwd>парогазовая установка</kwd><kwd>энергоэффективность.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hydrogen</kwd><kwd>methane-hydrogen mixture</kwd><kwd>combined-cycle plant</kwd><kwd>energy efficiency.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Министерства науки и высшего образования Российской Федерации в рамках Государственного задания № FSWF-2023-0014 (Соглашение № 075-03-2023-383 от 18 января 2023 г.) в сфере научной деятельности на 2023-2025 гг.</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">Cecere D., Giacomazzi E., Di Nardo A., Calchetti G.
