Steam Traps on Desuperheaters

Steam Traps on Desuperheaters

Steam Traps on Desuperheaters

Has anyone had any experience in sizing steam traps after a desuperheating station on steam lines. My logically thinking is that the trap (or traps) should be sized to drain water that may be inject by the spraywater system as follows:

1. As in our case the steam flow is not constant and there is the possibility that the spraywater control valve may pass or even fail open when not in use.

2. Steam trapping is sized to cope with the spraywater that is injected based on the spraywater control valve going fully open with a normal upstream operating pressure.

Is my thinking correct?

Look forward to some responses.



RE: Steam Traps on Desuperheaters

It seems that you will have superheated steam in most any-event, just with poor temperature control.  Steam trap is likely just for start-up use, when large volumes of condensate can form in lines?  Desuperheater/attemporator supplier could likely help you there, as well as ASME codes; sorry wasn't of much more help ...
