چکیده مقاله
The global demand for sustainable energy and the urgency to combat climate change have driven advancements in energy systems, particularly in gas turbine installations. The supercritical carbon dioxide (SCO₂) Brayton cycle has emerged as a promising solution, offering exceptional thermal efficiency, compact design, and adaptability across diverse power generation sources such as solar, biomass, and nuclear. At the heart of this cycle’s success lies the development of high-efficiency heat exchangers, including cutting-edge printed circuit heat exchangers (PCHEs). These exchangers not only enhance thermal performance but also improve startup efficiency, enable precise temperature control, and facilitate effective waste heat recovery. Additionally, they contribute to noise and vibration reduction, ensuring safer and more stable operation. This paper delves into the transformative role of high-efficiency heat exchangers in externally heated gas turbine systems, exploring their design innovations, operational benefits, and implications for environmental sustainability. Advancements in PCHE technology, such as improved heat transfer coefficients and material resilience under extreme conditions, are discussed alongside their application in Brayton cycles and cogeneration systems. The study underscores the critical importance of optimizing heat exchangers to maximize energy efficiency and reduce emissions, paving the way for more sustainable and efficient gas turbine technologies.
