These
heavy steel tanks receive the blowdown water from a
boiler and cool it down using the flash steam
principle, along with convection cooling over
several hours for the retained hot water. The tank
is designed to breakup the blowdown flow by
impacting the high pressure hot water on the steel
centrifugal impact plate. The water droplets give up
heat as flash steam is formed. The flash steam is
vented from the top of the tank to the atomsphere.
Retained water displaces cooled water from the
previous blowdown, and is retained in the tank until
it cools to the statute limits.
Data
required for sizing calculations:
Blowdown pipe size, type and equivalent length to
tank.
Boiler steam drum diameter & length.
Boiler operating pressure.

1)
Shell length (Dimension A) and connections size
dimensions can be changed to meet the
application requirements for the specific boiler
as determined be design rule calculations.
2) Sizing of tank and connections should be
determined using National Board design rules for blowoff tanks.
3) Construction: ASME Section VIII, Div. 1, 50
PSI DWP, with National Board serial number
