Targeted customization for 350 MW control-stage severe working conditions. Customize airfoil profile, fork-type blade root, 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
3D-Aerodynamic Optimization for Wide-Range Variable-Load Operation
Multi-stage CFD simulation optimizes blade profile for control-stage partial-admission characteristics. Effectively reduce flow loss and improve control-stage efficiency under wide operating load range.
Excellent High-Temperature Strength & Anti-Fatigue Performance
Premium heat-resistant alloy material with outstanding resistance against high-temperature creep, steam oxidation, thermal fatigue and solid-particle erosion. Reliable performance under frequent start-stop, peak-shaving and variable-load operation.
High-Precision Machined Robust Blade Root
Strict tolerance control for fork-type blade root, realizing stable and reliable blade-rotor connection. Good vibration-suppression performance, avoiding resonance risk and lowering high-speed rotating fatigue risk for long-term stable operation.
Strict Full-Process Quality Assurance
Raw-material certification, multi-item NDT non-destructive testing, dimensional inspection and surface integrity verification. Fully comply with large-power-generation equipment standards for both base-load and cycling-mode service.
Superior Lifecycle Economic Benefits
Improve unit availability, reduce unplanned outage risks, extend blade service cycle, and cut maintenance frequency and overall OPEX for 350 MW power-generation assets.
