Targeted customization for 600 MW control-stage harsh conditions. Customize airfoil profile, fir-tree root structure, dimensional tolerance and surface strengthening treatment per drawings or renovation schemes. Perfectly match original rotor wheel groove, minimizing on-site modification workload.
Key Features & Benefits
High-Load-Oriented 3D Aerodynamic Optimization: Multi-stage CFD simulation optimizes blade profile for control-stage variable-load characteristics, effectively reducing flow loss and improving control-stage efficiency under wide operating ranges.
Superior High-Temperature Strength & Anti-Fatigue Performance: Premium heat-resistant alloy material provides outstanding resistance against high-temperature creep, steam oxidation, thermal fatigue and solid-particle erosion. Reliable performance under frequent load regulation, start-stop and peak-shaving operation.
High-Precision Fir-Tree Root Structure: Strict tolerance control for fir-tree root ensures stable and reliable blade-rotor connection. Excellent vibration-suppression performance effectively lowers high-speed rotating fatigue risk for long-term stable operation.
Full-Process Strict Quality Assurance: Comprehensive quality control including raw-material certification, multi-item NDT non-destructive testing, dimensional inspection and surface integrity verification. Fully compliant with large-power-generation equipment standards for both base-load and cycling-mode service.
Remarkable Lifecycle Economic Benefits: Improves unit operating availability, reduces unplanned outage risks, extends blade service cycle, and cuts maintenance frequency and overall OPEX for 600 MW power-generation assets.
