Editorial
Spring forward with innovation
As April unfolds, the heat exchanger industry continues to evolve, bringing with it an array of innovative solutions, insightful experiences, and critical case studies that push the boundaries of thermal efficiency. This month’ s edition of Heat Exchanger World captures the spirit of progress through a compelling mix of expert insights and technological advancements.
Our cover story takes us into the world of nuclear heat exchangers, where Rolls-Royce SMR’ s Katrina Bradley shares her journey designing modular solutions for next-generation nuclear reactors. As the industry focuses on efficiency, safety, and scalability, Katrina’ s work exemplifies the crucial role heat exchangers play in ensuring these reactors meet strict regulatory and operational standards. Her insights into material selection, modular design challenges, and balancing efficiency with safety make this a must-read for professionals looking to understand the future of nuclear heat transfer. Don’ t miss it on page 8.
Meanwhile, Kelvion’ s article on carbon capture technologies on page 24 explores the heat transfer challenges in various carbon capture and storage( CCS) methods, from amine-based absorption to cryogenic carbon capture and direct air capture. As industries worldwide intensify their efforts to combat climate change, efficient heat exchangers are becoming pivotal in optimizing energy use and enhancing the feasibility of large-scale CCS deployment.
On the case study front, Immad Ovais Rohela, Olayan Descon Industrial Company, and Ahmad Raza Khan Rana, Integrity Products & Supplies Inc, dive deep into the failure analysis of duplex stainless steel heat exchangers presenting critical lessons on material compatibility and design integrity. The study dissects mechanical stresses, dissimilar metal weld cracking, and fatigue failure due to thermal cycling, highlighting the importance of thorough engineering reviews when repairing heat exchangers in corrosive environments. Read all about it on page 28.
And last but not least, turn to page 48 to learn our exciting update on Heat Exchanger World Europe Conference & Expo 2026. Before we kick off our preparations with the Call for Papers, there are a few important announcements we’ d like to share with you.
This month’ s article lineup reflects a common theme— continuous learning and adaptation. Whether it’ s leveraging nuclear advancements, optimizing carbon capture efficiency, or refining material selection in demanding applications, the heat exchanger industry is steadfast in its pursuit of excellence.
We hope this issue inspires you to explore new solutions, exchange knowledge, and drive innovation in your own projects. As always, we welcome your thoughts and contributions to keep the conversation moving forward.
All the best, Iryna Mukha Editor i. mukha @ kci-world. com
