SibCOTES Suggested Options for Verkhnetagilskaya Plant Development
OREANDA-NEWS. January 26, 2009. Engineers from SibCOTES have carried out an energy audit and prepared a feasibility study showing the first-priority measures to ensure proper energy saving and improve production efficiency at the Verkhnetagilskaya GRES (power plant) in Sverdlovsk Region.
The Verkhnetagilskaya GRES was commissioned over 60 years ago and its equipment had outlived its usefulness. Many installations meet neither existing operation conditions, nor the requirements set by the current codes.
To solve the problems faced by the power plant the engineers from SibCOTES suggested the following:
Cycle arrangement improvement;
Changed start-up and shut down systems for the units,
Implementation of the system for condensate gathering and polishing, changing of the existing system for boiler makeup, switching to more efficient technology for boiler mothballing;
Measures in terms of the turbine and boiler equipment (need to stop co-combustion of coal and gas in the boilers was validated);
Measures for flue gas cleaning to ensure standard environmental performance;
Rehabilitation of hydraulic ash handling system;
Range of measures to improve the system for engineering-and-economical performance recording.
To improve engineering-and-economical performance at the Verkhnetagilskaya GRES engineers from SibCOTES recommended the measures for its equipment to be used in the best possible way.
The project presents four options for the power plant development concept depending on the fuel strategy chosen – construction of a combined-cycle plant, construction of pulverized coal-firing power generating units, replacement of 90 ata equipment with more cost-efficient equipment within the existing main building, and decommissioning of equipment.
The solutions suggested will enable the customer to greatly improve the efficiency and reliability of the power plant operation. For all the measures considered, SibCOTES provided specific engineering solutions, cost estimations, calculations for the equipment application efficiency.
