Noise in the steam pipeline for the reboiler
Thread Content
What causes the noise in the steam pipeline used for the reboiler, with intermittent whistling sounds?
It may be caused by uneven flow velocity in the reboiler tube bundle.
This could be caused by a malfunctioning steam outlet trap; it is necessary to check the condition of that trap!
There is no steam trap at the back; there is a steam expansion vessel instead
Then we could consider lowering the pressure of the steam expander slightly to see if the noise is still present
Not bad, let’s change the pressure and see if it’s still the same
