The domestically developed F-class gas turbine's first-stage rotor blade of "Huadian Ruiyi" by China Huadian Corporation has logged over 2,000 cumulative hours of operation at the Qishuyan Power Generation Company in Jiangsu Province, setting a new national record for operational longevity in F-class heavy-duty gas turbines. This rotor blade has significantly contributed to peak power supply in Eastern China, successfully navigating over 100 gas turbine startups, thereby demonstrating its resilience to high temperatures and the robustness of its manufacturing process. This achievement signifies that China has attained full mastery over the entire lifecycle of F-class heavy-duty gas turbines' core high-temperature components, encompassing design, manufacturing, processing, testing, and service evaluation. Looking ahead, China Huadian aims to further bolster the technology of heavy-duty gas turbine key components and drive the optimization and upgrading of the gas turbine industry and energy structure.
