Customized 135 MW Steam Turbine LP Moving Blade with 3D-Optimized Aerodynamic Design Anti-Water-Droplet-Erosion and Precision-Machined Root

Dedicated customization for 135 MW LP unit conditions. We customize blade airfoil profile, root structure, tip geometry, dimensional tolerance and surface treatment per drawings or renovation schemes. Perfectly match original rotor wheel groove, minimizing on-site modification workload.

• 3D-Optimized Aerodynamic Design: Multi-stage CFD simulation optimizes twisted-tapered blade profile. Effectively reduces secondary flow loss, tip leakage loss and wet-steam flow loss. Improves low-pressure stage efficiency, lowers unit heat-rate and coal consumption.
• Outstanding Anti-Water-Droplet-Erosion & Anti-Fatigue Performance: Premium martensitic stainless steel material with excellent resistance against water-droplet erosion, steam oxidation and thermal fatigue. Adapts to long-term wet-steam environment, frequent start-stop and peak-shaving variable-load operation. Optional hard-facing treatment for last-stage blades for enhanced anti-erosion capacity.
• Precision-Machined Reliable Blade Root: Strict tolerance control for blade root guarantees stable connection with rotor. Good vibration-damping capability reduces high-speed rotating fatigue risk, adapting to flexible cycling operation of 135 MW power-generating units.
• Strict Full-Process Quality Assurance: Raw-material certification, multi-item NDT non-destructive testing, dimensional inspection and surface integrity verification. Complies with power-generation equipment standards for both base-load and cycling-mode service.
• Excellent Lifecycle Economic Benefits: Improves unit availability, reduces unplanned outage risks, extends blade service cycle, and cuts maintenance frequency and overall OPEX for 135 MW power-generation assets.
