AI Technical Summary
Existing technologies struggle to accurately identify localized high-stress zones in high-parameter steam pipelines, resulting in insufficient safety and reliability of temperature and pressure monitoring point locations. In particular, with the adoption of new high-temperature alloy materials, traditional methods and software simulations are inadequate to meet the needs of high-parameter coal-fired power units.
By combining computational fluid dynamics and structural finite element analysis, a variable operating condition model of the thermodynamic system is established, multi-factor coupling analysis is performed, high-stress areas are identified and avoided, and safe installation areas for temperature and pressure measurement points are determined.
It ensures the safety and reliability of temperature and pressure measurement point locations across the entire operating range of high-parameter coal-fired power units, accurately identifies and avoids local high-stress danger zones, and ensures the structural safety and long-term monitoring reliability of the measurement points.
