Modernization of turbine equipment

JSC “Poltava Turbomechanical Plant“  develops and implements modernization projects of existing steam turbines with a capacity of up to 300 MW.

The main tasks that are solved by the modernization of steam turbines:

  • increase of thermal and electric capacity;
  • increasing efficiency;
  • increase in reliability and maintainability;
  • increased maneuverability;
  • restoration of the work resource;
  • improvement of operational characteristics

The main technical solutions implemented in JSC “PTMZ” steam turbine modernization projects:

  • modernization of flow parts with the production of nodes of a new, more advanced design with improved technical and economic indicators;
  • modernization of the heating scheme of flanges and studs;
  • optimization of temperature expansions;
  • modernization of steam distribution and regulation units with the introduction of a modern electro-hydraulic regulation system;
  • supply of modern systems of control of mechanical quantities and vibration of the turbine;
  • repair or replacement of auxiliary equipment;
  • tying of new equipment to the existing conditions of the station.

When implementing steam turbine equipment modernization projects, JSC “Poltava Turbomechanical Plant” is ready to undertake contracting, service and chief installation services. The service department of the plant provides support for the operation of modernized equipment.
