Servicing of 50-1200 MW steam turbines for TPP and NPP
Full or partial modernization of high-, intermediate- and low-pressure cylinders with or without steam-flow rate buildup in order to increase power and efficiency by 2 to 12% and reduce specific fuel consumption by 3 to 10% (depending on the scope of the overhaul, initial equipment condition and local conditions).
Process extraction steam turbine modernization in order to increase their throughput due to reduced steam consumption for production purposes.
Turbine overhaul in order to adapt the main and auxiliary equipment of the unit to the combined cycle.
Provision of additional extractions from the high-, intermediate- or low-pressure cylinders of 60 to 300 MW turbines to meet customers’ requirements in process- and heating-steam extractions.
Installation of 25 to 70 MW supplementary turbines utilizing unused process bleed steam.
Provision of controlled heating-steam extractions for 200 to 1200 MW condensing turbines to achieve a thermal power of 100 to 500 GCal/h.
Modernization of valves, steam distribution and control systems.
Modernization of control, vibration monitoring and diagnostics systems.
Condenser replacement and auxiliary equipment enhancement.
Hydraulic turbine servicing
Replacing runners with more efficient ones.
Replacing the runner blades of Kaplan turbines.
Replacing hydraulic turbine guide vanes.
Replacing unit bearings and shaft seals.
Replacing electromechanical governors with electronic governors.
Replacing flowpath component materials with cavitation-resistant ones.
Installation of polymer guide vanes and bearings not requiring lubrication in runner friction components.
