ADVANCED ULTRA-SUPERCRITICAL BOILER TECHNOLOGY IN THERMAL POWER PLANTS: INNOVATIONS IN MATERIALS, DESIGN, AND OPERATIONAL EFFICIENCY

Advanced ultra-supercritical (AUSC) boiler technology represents a major breakthrough in power generation since it offers lower emissions and better thermal efficiency than traditional subcritical and supercritical systems. The most recent advancements in materials, designs, and operating techniques that are propelling the development of AUSC boilers are closely examined in this review article. Because they can tolerate the high temperatures and pressures involved in AUSC operation, advanced materials like thermal barrier coatings and nickel-based superalloys are highlighted as having the potential to increase durability and lower maintenance costs. Studies of global AUSC boiler implementations underscore the practical applications of these advancements and offer insights into best practices and lessons learned. The development of next-generation materials and the use of carbon capture technologies are just two examples of the trends and directions that the article examines for future research. By identifying upcoming challenges and synthesizing current knowledge, this review aims to provide a comprehensive resource to optimize AUSC boiler technology for a more efficient and sustainable energy future.
