Specification of HP Turbine(500 MW):

• Main Steam Temp- 537˚C• main steam pressure- 170 kg/cm2

• Reheat steam temp- 537˚C• Length of Rotor- 4.61m• Height- 2.15m • Weight- 86400kg

1. H.P TURBINE-

05/01/202313

The blades are responsible for extracting energy from the high temperature, high pressure steam produced by the  boiler.

H.P Turbine Blades:

05/01/202314

I.P Turbine have more pressure than L.P Turbine but less than H.P Turbine. Specifications of I.P Turbine:

• Length- 4425 mm • Width- 5000 mm• Height- 4800 mm• Steam pressure- 41 Kg/cm• Steam temperature- 537˚C

2. I.P TURBINE-

05/01/202315

The size of blades of I.P steam turbine is larger than H.P steam turbine, but smaller than L.P steam turbine.

I.P Turbine Blades:
