THERMAL POWER PLANT PRESSURE PARTS PRE-ASSEMBLY PHOTOES.

We are discussing about super heaters of a super critical boiler. It is felt prudent to attach

a few pictures of different pressure part items in the write up. Number of major pre-assembly

has been carried out in pressure parts and the same is also attached herewith.


This was  pre-assembled  inside the boiler cavity after preparing a bed for its assembly. We

have used two 10 MT winches with multi sheave pulleys to place it in position. Two cranes

are also used to tail the assembly during erection . Otherwise there is every possible chance

that the panel will get bend on its own weight . The total weight will be around 60 MT.


Pre-assembly of different headers with loose tubes were done and kept ready. It can be seen few

tubes are left behind due to facilitate the erection hardware fitting and alignment afterwards. Also

in the picture spiral wall pre-assembly is going on.
