Flash Tank Sizing Standard
Flash Tank Sizing Standard
(OP)
Does anyone know any information pertaining to sizing Flash Tanks for steam systems. I am wondering if there is a standard that I must adhear to or if sizing a Flash Tank is simply left up to what the distributer's specs call for.
Thanks for any help.

You could try the Canadian Boiler, Pressure Vessel and Pressure Piping Code B51-97, Part 1

The people at Penn separator have always been helpful to me

They offer sized systems based on the boiler capacity, pressure and expected blowdown rate.
I had some ancient ASME papers, from the 1940's on this topic.....developed by a former Stone & Webster Vice president.....I had 'em......but I lost them
I am aware of no recent engineering textor article on this subject.

One of the more important governing factors is the limiting of the upflow velocity of the steam vapor to prevent entrainment of moisture droplets.
There is a good discussion of this issue in another forum in this site, so you might try a search in Eng-tips.

Your internet link was quite helpful. The National Board of Boiler and Pressure Vessel inspectors provides a document called "A Guide for Blowoff Vessels" where they identify a good target velocity for the steam vapor of 11 ft/sec to allow for proper seperation.

Im not having any luck locating the discussion you made reference to (I'm rather new on this website) and I was hoping you could point me more in the right direction. Thank again for your help.
