technical NOTES

(Project Pridr) #1

Construction



  1. A frame type construction with tube bundle having separate condensing (primary)
    and air evacuation (dephlagmetor) sections.

  2. Large diameter low speed fans driven through gear box by AC motors are used
    in forced draft mode pushing atmospheric air from below to the tube bundles
    mounted on the A-Frame.

  3. All round wind wall and module partition walls prevents hot air recirculation.

  4. The condensed steam (condensate) is collected in condensate storage tank and
    pumped to the de-aerator as feed water to the boiler.

  5. Tube bundles Fans either in FRP or Aluminum construction driven by gear box.

  6. A-frame mounting structure.

  7. Wind wall to arrest cross winds & avoid recirculation.

  8. Steam duct from turbine exhaust frame to condenser with expansion bellows.

  9. 2 x 100% holding ejectors and 1 x 100% hogging ejector.

  10. Condensate and hot well drain tanks.

  11. Condensate extraction pumps & Hot well pumps.
