This study investigates the utilization of waste heat from the exhaust gases of boilers in small power steam-gas type power plants using heat pumps. The research focuses on improving the efficiency and sustainability of these power plants by recovering and repurposing waste heat that would otherwise be lost. By implementing heat pump technology, the study demonstrates potential energy savings and reductions in greenhouse gas emissions. Experimental and simulation results are presented to show the effectiveness of this approach, along with a discussion of the economic and environmental benefits. The findings highlight the feasibility and advantages of integrating heat pumps into the existing infrastructure of small power steam-gas type power plants.

В работе исследуется утилизация отработанного тепла отходящих газов котлов электростанций парогазового типа малой мощности с использованием тепловых насосов. Исследование сосредоточено на повышении эффективности и устойчивости этих электростанций за счет рекуперации и повторного использования отходящего тепла, которое в противном случае было бы потеряно. Исследование демонстрирует потенциальную экономию энергии и сокращение выбросов парниковых газов за счет внедрения технологии тепловых насосов. Представлены результаты экспериментов и моделирования, показывающие эффективность этого подхода, а также обсуждение экономических и экологических преимуществ. Полученные результаты подчеркивают целесообразность и преимущества интеграции тепловых насосов в существующую инфраструктуру малых электростанций парогазового типа.

Ushbu tadqiqotda kichik quvvatli bug‘-gaz turidagi elektr stansiyalari qozonlarining chiqib ketuvchi gazlaridagi chiqindi issiqlikdan issiqlik nasoslari yordamida foydalanish o‘rganiladi. Tadqiqot aks holda yo‘qolib ketadigan chiqindi issiqlikni utilizatsiya qilish va undan qayta foydalanish orqali ushbu elektr stansiyalarining samaradorligi va barqarorligini oshirishga qaratilgan. Issiqlik nasosi texnologiyasini joriy etish orqali tadqiqot energiyani tejash va issiqxona gazlari chiqindilarini kamaytirish imkoniyatlarini namoyish etadi. Ushbu yondashuvning samaradorligini ko‘rsatish uchun eksperimental va simulyatsiya natijalari, shuningdek, iqtisodiy va ekologik afzalliklar muhokamasi keltirilgan. Olingan natijalar issiqlik nasoslarini kichik quvvatli bug‘-gaz turidagi elektr stansiyalarining mavjud infratuzilmasiga integratsiya qilishning maqsadga muvofiqligi va afzalliklarini ta‘kidlaydi.
