Same sort of emitted electrode as well as collecting plate damage in B-PASS . It’s under maintenance.

Condensate storage tank (500 kl)
5th units as well as 6th unit CS tank are ready


2 no Degasified tank (100 kl) and 2 no of DMST (800 kl) are fabricated and tested on site. DM plant BED placed and piping arrangement is under progress .N.Pit pumps are placed & out of 4 one alignment completed. Two regeneration pump’s foundation work completed.

Necessary action may please be taken to overcome the following constraints for erection of DM plant.

1. Caustic measuring tank (2nos) and Acid measuring tank (2nos) to regeneration
line yet to complete due to not availability of 4nos ejector.
2. Mix bed outlet to DMST pipe line (150nb) yet to complete due to material
non supply.
3. Regeneration power water line (65nb) from degasser water discharge line
to preparation tank yet to complete due to material non supply.
4. Hume pipe not available in site due to which the underground connection
between DM feed water pump to ACF including road crossing not completed.
5. PVC flooring work as well as HDPE pipe arrangement work is suspended due
to ground water leakage in N-Pit.
6. PVC flooring in N-pit drain yet to complete due to balance civil finishing work.
7. Degasser blower yet to erected due to foundation work.
8. Hot water tank heater not available in the site.
9. SS pipe welding under progress.
10. SBA outlet valve erected in odd position.
11. All vent line & valve are misalignment.
12. Foundation of bulk acid fume absorber is misaligned.
13. Safety shower still not erected but drawing does not show any over head tank
14. Grouting bolt out of pocket of Weak base anion exchanger (R3B-WBA),
Strong base anion exchanger (R4B-SBA) & mixed bed exchanger (R5B-MB).
Due to out of pocket they have welded extra piece of MS Plate
which is undesirable.
15. More number of seams placed under the filters legs. Thickness are
mentioned bellow:
a. R3A-WBA-80mm, 50mm, 60mm, 50mm.
b. R2A-SAC-40mm,45mm,65mm,50mm.
c. R1A-ACF-20mm,30mm,50mm..
16. Bulk acid storage tank foundation broken at contact between foundation & tank.
17. Air line connection from compressor to DM plant out side.
18. Lighting not yet started.
19. Earthing inside DM & regeneration building not yet started.
20. Electrical connection to all motor not yet started.


Apart from monorail as well as shading almost all the mechanical job is completed. All the twelve CT fans are available for operation.

CW PUMP HOUSE: Two nos CW and two nos ACW are available for operation and the remaining CW pump is ready from the mechanical side. EOT crane erection over.

RAW WATER PIPE LINE: Pipe laying (914 NB) is almost 80% completed and UT of that portion is going on.

RAW WATER PUMP HOUSE:
One ash water makes pump, one CHP dust suspension pump &one raw water pump are
Grouting only completed so far.


Almost all the major portion of CHP is completed and operation is going on. Few pending jobs in bunker floor are in

advanced stage.
