High-Pressure Turbine Cylinder Assembly for T-100-130 Upgrade Applications

The project of modernisation of turbine T-100-130 provides for replacement of units and parts of the turbine operating at high temperatures and exhausted resource, and includes types of works - replacement of:
- complete DDC and CSD with installation on the existing foundation and new housings of the front bearing block and middle (thrust bearing) bearing
- control and locking valves
- cam-type distributor of the UA control valves
- CND flow section
- control diaphragm servomotor
- foundation frames under the housings of the front bearing block and the centre (thrust) bearing block
- two safety valves on the lower heating extraction pipeline for one safety valve
- organisation of additional steam extraction behind the CVD from the bypass pipe of the CVD-CSD to the general station collector with a flow rate of up to 70 t/h.
Designation of the turbine after Modernisation: T-110/120-12,8 PR2.
