Sizing For A Boiler Blowdown Tank?
Sizing For A Boiler Blowdown Tank?
(OP)
Hey everyone,
First post, so here it goes.
I'm having trouble in finding how to choose the correct size for the tank. I recently did research on Flash Tanks and found sizing information on them was very readily available, but it is quite the opposite for blowdown tanks. My first thoughts were that the size of the tank would correspond to the boiler (pressure, flowrate, volume) but I could very well be way off-base, as this is my first time dealing with boilers and boiler applications.
Any help is very much appreciated!

So, be careful. Find out from your boiler manufacturer how much water it takes to lower the level by: 4 inches?, or should it be some other value per the mfr????
Always check with the boiler mfr. Do not guess.

Table 1 defines the design pressure for blowoff vessel
Max boiler pressure 15-300 psi use 30% of max boiler pressure but shall be at least 15 psi
Over 300 psi max boiler pressure use 100 psi.
Table 3 defines size
foe example 25000 lb/hr boiler use 42" dia x 40 ft3 volume
