Fir-tree Root,Curved Fir-tree Root Rotor Blade

The core difference between Straight Fir-tree and Curved Fir-tree rotor blades lies in the root serration profile and the wheel groove alignment: The former features straight serrations with Axial Entry, making it suitable for High and Intermediate Pressure stages and medium-length blades. The latter features curved serrations with Side Entry (or Curved Axial Entry), making it better suited for Long Blades in the Low Pressure (LP) Cylinder. This design reduces stress concentration and improves root-to-tip flow path matching.

Application

Straight Fir-tree roots are commonly used in the High and Intermediate Pressure stages of 600MW/1000MW units;  whereas Curved Fir-tree roots are mostly used in the Last Stage or Penultimate Stage of the Low Pressure cylinder, featuring Integral Shrouds and Snubbers (Tie-bosses) to coordinate with the moisture removal system.
