The majority of main and auxiliary equipment within thermal power plants built and operated during the Soviet era has now expired and is thus in need of replacement or refurbishment. We are ready to offer all measures necessary for the repair and/or improvement of equipment. COTES posseses profound experience and a highly qualified team of engineers.
As a rule, we begin the first stage by performing a detailed examination of the main and auxiliary equipment, as well as the subsystems. The engineers determine the current condition and operational limitations before going on to develop options for the retrofit. Retrofit plans are tailored to be the most efficient for a given facility, based on the engineering calculations and the implementation experience gained from work on other facilities. If necessary, the engineering solutions are accompanied by an evaluation of the capital costs of retrofitting and payback options where relevant.
Examples of retrofits aimed at improving generation facilities’ efficiency and reliability:
- TPP heat scheme optimization.
- Retrofitting operating boiler equipment through refurbishment of burning systems, furnaces and burners.
- Turbine equipment refurbishment.
- Conversions to off-design fuels.
- Black oil-free ignition and flare stabilization of pulverized coal boilers by electroionization.
- Boiler heating surface cleaning systems.
- Dry ash handling systems and solid fuel burning products’ efficient use.
