Flash Tank, Sparge/Spray Pipe ??????
Flash Tank, Sparge/Spray Pipe ??????
(OP)
Hello folks,
I've got a 20" dia x 48" long horizontal steam condensate flash tank. Tank is vented to atmosphere. 60lb steam condensate at about 4000 lbs/hr, approx 400 lbs/hr flash steam. Question is the existing tank has a spray or sparge pipe installed at the inlet to the tank. Sparge pipe is 42" long with 48 1/4" dia holes. Sparge pipe is above the waterline (waterline is 1/2 up the tank).
Does anyone know what the sparge/spray pipe is really supposed to do? Also does anyone know what the sizing parameters/methods/guidelines would be for this sparge pipe would be? The tank manufacturer states in their literature that the sum of the sparge pipe holes equals or exceeds the cross sectional area of the inlet. Might this mean that conventional condensate line sizing would be used to size the sparge pipe/inlet?
-Thanks for any ideas.

Another thing it does is the same thing the aerator does in your kitchen faucet: it divides the flow into many small jets instead of one huge jet. THe flow exits radially, canceling much of the pipe loading. Steam hammer in a non-sparger-equipped tank could rip the pipe out if left unmitigated.

Are you sure your tank is not installed upside down?? Just kidding, but above the water line the sparge pipe will have no real effect that I can see.
BTW: I never liked these sparge pipe tanks, where I always see some 'pinging' from thermal water hammer, and also see errosion/corrosion on the sparge pipe even though most are made from stainless.
