BRIEF DESCRIPTION OF WORKS:
For Improvement of Boiler Performance, NTPC Ltd. has decided to incorporate some Boiler Modifications as mentioned
below at NTPC, Talcher-Kaniha in its Stage-II Units. It is intended to carry out modification work in Unit V of ST-II
during FY 2018-19 under this Contract.
a. Installation of additional bank of LTSH (Low Temperature Superheater):
Presently, there are two banks of LTSH Coils above the Economiser located in the 2nd pass. There is sufficient space
above the existing upper bank of the LTSH and it has been planned to add another LTSH bank in this available space.
This new LTSH Bank shall be of 130 coils (65 pairs) loaded on four rows of hanger tubes, similar to existing LTSH
Upper bank. Each coil shall be having 12 tubes of size: 47.63 mm OD x 6.6 mm thickness and material SA 213
T11grade.
b. Replacement of 23 panels in Final Reheater:
There are 78 Panels of Reheater. The Reheater is in two stages. One set of panels are Reheater Inlet panels and the
other set of Panels is final reheater panels. There are 12 circuits in each panel. The panels are numbered from 1 to 78
from Boiler left to boiler right. The right 23 panels are intended for replacement completely. Presently, it comprises of
T91 and T22 tubes of size: 54 mm OD x 4.5 mm. Now, it has been planned to replace the same with Stainless steel
material of type SA213 TP 347 grade of tube size: 54 mm OD x 4.5 mm. These loops shall be connected to the new
Siamese headers by the connecting bent tubes in the outlet side and shall be connected to the inlet side at the marked
portion in the drawings.
c. Removal of First Six Circuits & Installation of Four Loops in Final Reheater Panel Nos.1 to 55:
As mentioned above, there are 78 panels of reheater. The reheater is in two stages. The panels are numbered from 1 to
78 from Boiler left side to Boiler right side. In Unit-V, First two loops of RH Outlet all 78 coils shall be removed
permanently and at the Inlet header, they will be made dummy. The next four loops of the Final reheater panels
numbered from 1 to 55 shall be replaced with Stainless steel as per SA 213 TP 347 loops. Presently, it comprises of
T91 and T22 tubes of size: 54 mm OD x 4.5 mm. Now, it has been planned to replace the same with Stainless steel
material of type SA213 TP 347 grade of tube size: 54 mm OD x 4.5 mm. These loops shall be connected to the new
Siamese headers by the connecting bent tubes and shall be connected to the inlet side at the marked portion in the
drawings.
.
d. Replacement of Single Reheater Outlet Header with Siamese Headers:
Presently, the final reheater loops are all connected to a single reheater header. This header is the outlet header and it
discharges hot steam at desired steam parameters to IPT. It is intended to replace this single header with two different
Siamese headers. Half of the final reheater tubes shall be connected to one Header and the other half shall be connected
to the other header.
e. Modification of Crisscross connection in the Superheater Circuit Headers:
The steam from the Boiler drum goes to Low Temp. Super Heater (LTSH), first stage of superheating process. After
heating in LTSH coils, it goes to the LTSH Outlet Header. From the LTSH Outlet Header, steam goes to Divisional
Superheater Inlet header. The Steam after getting superheated in the Divisional Superheater goes to the outlet header. The
Steam from the Divisional panel outlet header goes to the Inlet header of the Platen Superheater, where it gets further
superheated and finally goes to the Platen super heater outlet header and moves to HPT as Main steam.
Presently, the LTSH Outlet header and the Divisional panel inlet header are connected criss-cross by means of connecting
pipes whereas the Divisional Panel Outlet header to the Platen Superheater Inlet header is connected straight through by
means of connecting pipes. Now, it is intended that the criss-cross connection between the LTSH Outlet header and the
Divisional panel inlet header shall be connected straight through whereas the Divisional Panel Outlet header to the Platen
Superheater Inlet header shall be connected as criss-cross.
f. General:
It is intended to have a total of approximately 2500 HP weld joints in LTSH, 1110 nos. T-91 HP joints of tubes, 450
nos. T22 HP joints, approx. 1275 nos. SS 347 HP weld joints in Reheater area. In addition, there will be 30 nos. Pipe
joints (12 nos. between Platen-Divisional headers, 8 nos. between LTSH-Divisional headers, 4 nos. between Reheater
Siamese headers and 6 nos. in HRH piping)
