Heavy 325MW Gas Turbine Generators with Steam Turbine CCPP
Structural Characteristics
- High-flow, high-pressure-ratio and high-efficiency compressor with anti-corrosion coating applied on the first four stages
- Central tie-rod rotor featuring high torque, high rigidity, self-centering performance and excellent thermal inertia
- Two-stage adjustable guide vanes with ample anti-surge margin and high part-load efficiency
- Four-stage turbine adopting double-casing structure, equipped with air cooling system and thermal barrier coatings to improve overall unit efficiency
- Annular combustion chamber insulated by ceramic and metal tiles, enabling independent disassembly for easy maintenance and inspection
