Desuperheater Installation
Desuperheater Installation
(OP)
Dear Friends.
What is the purpose of desuperheater installed in the HP steam lines behind steam drum of power boiler?
I guess it's letting steam down.
Is it right?
Thanks.

RE: Desuperheater Installation
refer to standard texts such as B+W "Steam" for the general design philosophy for these items.
RE: Desuperheater Installation
I would add to your own sentence "I guess it's letting steam down.." "the right amount" I mean if you're producing superheated steam it's not to lower it down the saturation temperature!
the de-super heater is mainly installed to control the temperature/pressure of the superheated steam produced.
The superheated steam produced is generally a bit hotter than needed, that's why we regulate (divert) a certain amount (flow)to this equipment (which is open to atmosphere) if I am not wrong it looks like a small drum in the top of the boiler structure from where you see in normal operations, steam going out.
Sorry for my long speech.
