The project of modernisation of the turbine T-100/120-130-2 provides for delivery of a new DDC with a single regulating stage (RS) and nine pressure stages, as well as a number of other parts and assemblies, including a modernised cam distributor with a reinforced frame, modernised regulating and stop valves, support bearing with modernised thrust pads of increased bearing capacity. Heating of the flange connection of the DDC is made through the flange skirts of the DDC horizontal connector.
The VD rotor is made with a half coupling of the coupling coupling of the VD rotor and SD rotor.
Turbine modernisation provides:
- improvement of steam distribution operation;
- increase of turbine efficiency due to optimisation of the flow part.
Designation of the turbine after Modernisation: T-110/120-12,8 PR3-1.
