Failure of Aux boiler tubes.

Post by naseemce » Mon Sep 18, 2017 11:14 am

We have faced issue of failure of aux. boiler tubes .
We reviewed the process parameters for last two years and DM water quality . There was no significant change.

What can be the cause of sudden failure and how can be avoided in future?

Dear
There are so many reasons of failure of boiler tubes. Better u performe RCA and come to conclusion. Some reasons are as bellow
1) Tube's material
2) Weld joints
3) Water chemistry.
4) NDT checks not performed.
5) Thermal socks
6) Higher cyclic variation in boiler load
7) Dead zone etc.

Firstly Identify if it’s a water side or fire side issue. This will narrow down the investigation.

Please reply as appropriate.
