Sellection of Steam Trap
Sellection of Steam Trap
(OP)
Dear All,
Need your help in selection of a Steam Trap..
I got a exchanger which is operated on a temperature control, the condendate load is about 2600 lb/hr The operating pressure is 60 psig and the condensate is drained to atmosphere.
The vendor quoted me a 1.5" flat type trap with a capacity of 4500 lb/hr. He insists that is the size I should use becaue the manufacturer recommends 1.5 excess capacity over the normal capacity.
There is a 1" trap available which has a capacity of 3200 lb/hr. I think, 1" is more suitable.
I need your opinion.
Thanks in advance,
Timewrap.

RE: Sellection of Steam Trap
If your trap required 50% of the time to fill, then it would need 2X the flow rate to be able to vent what it had collected to keep up with your Hx.
A trap is not a level control valve, it is a trap.
And another tip; select a trap that has the capability to pass air (non-condensables.) The steam that will enter your Hx will have some air in it, typically. If the trap can't release it, it will build up in the Hx and eventually air bind it.
