Steam turbines

Main steam turbine types
К-1200-6,8/50 К-1000-60/3000-3 К-1000-60/3000-2
К-1000-60/3000 К-800-130/3000 К-200-130

These turbines boast a number of design features increasing their reliability and lifetime.

  • We use solid-forged low- and high-pressure rotors;
  • This enhances turbine operation reliability and reduces operating costs for additional inspections;
  • The double-flow design of the cylinders and their layout help to unload the thrust bearing;
  • We are using a new design for the support bearing with enhanced load-bearing capacity;
  • The special shape of the guide vanes ensures optimal steam distribution along the vane height and an increase in LPC and HPC efficiency;
  • Honeycomb shroud seals are used in the steam path of high- and low-pressure cylinders. This minimizes steam leakage and boosts efficiency;
  • The use of high-quality stainless steel in high-pressure cylinder enclosure parts makes it possible to prevent the negative effect of wet steam on the turbine’s critical parts and reduce repair costs.
  • We have created a new rotor blade for the last stage of the low-pressure cylinder. Titanium used to manufacture the blade ensures extremely-high strength properties;
  • The surface of the last turbine stages’ rotor blades is coated with a protective layer of titanium nitride, which prevents erosion wear, thus increasing equipment service life;
  • We have increased the rigidity of the foundations, enclosures and supports of new turbo-generating sets, which has enhanced their operational reliability.
Auxiliary equipment
  • turbogenerators of various types with a maximum capacity of 1200 MW;
  • heat-exchanging and auxiliary equipment;
  • excitation systems and start-up frequency converters;
  • drive turbines for feed pumps.
Service support

Along with equipment delivery, Power Machines provides the following services: technical supervision over installation activities; designer’s supervision; start-up, commissioning and warranty maintenance including participation in scheduled repairs; as well as consultancy support and customers’ personnel training.

Power Machines offers a complete package of services that covers the entire product lifecycle, including:

  • post-warranty service maintenance including the supply of spare parts and special materials;
  • regular preventive scheduled inspections and emergency maintenance;
  • renovation services (equipment parameters’ alignment with design levels);
  • modernization services (equipment parameters’ enhancement beyond design levels, including the replacement of major units and components);
  • overhaul services (significant enhancement of design parameters involving the replacement of all major parts and components, including their complete replacement with new equipment, if necessary).
