Pipe Bowing in a fired heater 2

[Zeyad Zahran]

Hello everyone,

I am investigating a problem of the bowing of the lower tubes of a VDU fired heater, what are the best approaches to prevent or mitigate this phenomenon.

Are there baffle supports? How the thermal expansion is taken care of?

A section drawing with thermal data will help understanding.

Not having cold liquid / hot vapour mix or vice versa.

Not much to go on here....

Before you mitigate it, you need to figure out what's causing the bowing in the first place.

What possible causes have you investigated?
