In order to have a strong and safestructural footing the columns are to beerected very carefully.
It can not be transported and erected insingle piece.
Utmost care is taken in the pre-assembly
stage to maintain the matching of columnend faces & to achieve verticality with intolerance limits.

Once the column erection is over up to the
full height, the cross beams are placed
securely over the columns which supports
the main boiler.
After that anchor point called ceiling girder
on the top of the boiler is constructed on
all the sides of the boiler so that loadtransfer could take place

BOILER DRUM LIFTING
Drum is to be lifted in horizontal position
Initially drum is to be lifted at a height of68mtrs
The level of the drum centre is to beverified by water level to ensure exactelevation of 72.511mtr

PRESSURE PARTS
Pressure parts is divided in to two passes
Erection of headers and water wall panel One side of water wall require 35 to 40
panels
Boiler walls are checked verticality andaxially with respect to boiler drum position
