steam desuperheating

[masg]

we are designing a steam desuperheater ahead of a reboiler. 600 psig, 700 degF steam is being let down to 300 psig. Would like to find a desuperheater that doesn't use a external or pumped condensate, rather educts the reboiler's condensate. One design requires the reboiler to be 25 feet above the desuperheater. One manufacturer's product we've used 15 years ago is no longer in this line of business. Does anyone still make such a device? <p>Steve Grzywa<br><a href=mailto:sgrzywa@citgo.com>sgrzywa@citgo.com</a><br><a href= > </a><br>

hi

if the pressure of the injected condesed is higher than superheat steam then it is possible to used this system.
the injected pressure of condesed should be calculated.

Check with Yarway, Graham, Copes-Vulcan, they should be able to help you. Trying

http://www.google.com

for steam desuperheaters, there are quite a few hits.

Chemical engineering puts out a vendor listing each year, you might search in that. I think they also had an article on different types of desuperheaters in the last couple of years, that would be a good starting point.

Sorry I don't have more details for you.
