Hydrogen Gas and other gas system.
De aerator ,Feed storage tank with all accessories.
Condenser and its
accessories.
Small system like Seal and leak off steam, condensate
polishing unit , Vacuum Pump system , different hoist , turbine drain system
Vibration Isolation system for TG foundation and drive turbine foundations.
Extraction systems , TG integral piping etc.
All the items ( except De aerator ) comes under the roof of
A-B Bay.
All the items are lifted by 02 Numbers EOT crane for small
units for bigger units like 500 MW and above stator is being lifted by Strand
jack method /by portal crane.
Above picture shows two turbine deck ( for unit -1 and unit -2). One unit stator lifting has been
completed and decks are already casted. In 2nd unit only bearing pedestal are erected ,aligned with
the centre line and secondary grouting has been completed. Stand for streching Piano wire is visible
at both end .
A typical drawing of turbine deck is attached herewith showing EP ( embeded parts) on the deck.
continued to part-II foundation checking before casting and after casting.
