The 150 MW turbines

We got a two turbine units. Both of them are a subject of the overhaul project and both of them are the 150 MW turbine but this feature will change as one of the project aims is to increase the trubine efficiency. The IP steam path is about to replace and two stages at LP rotor as well.
Let me present a drawing of this turbine:

1. HP part
It is impulse part with 18 stages, one outer casing, two bearings. The bearing no.1 is a radial one and the bearing no. 2 is a combined one axial-radial.

2. IP part
This has 15 stages and similar to HP, one casing, two radial bearings (no. 3 and 4)




3. LP part


A double-flow rotor, the two radial bearings (no.5 and 6), the rigid couplings

4.The Generator left in power plant, so no activities on our workshop linked with this turboset part - at least I do not know what is work scope for gen. parts.
