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.
turbogenerators of various types with a maximum capacity of 1200 MW;
