Flash Separator
• Reduces steam pressure or vents process steam
directly to atmosphere.
• Eliminates moisture from process steam (cyclonic
spinning mechanism permits the use of smaller tanks
to completely separate ash steam from condensate).
• ASME Section VIII “UE” stamped separator standard
up to model BFS-16-56.
• ASME Section VIII “U” stamped separator standard for
models BFS-16-56 and above.
• Sized to accommodate a given #/hour ow rate of
steam from a given source psig to a given vent psig.
• Model Range:
6" diameter x 34" high through
36" diameter x 108" high
• Modular conguration to meet customer requirements
include: a ash separator and the following options:
trap, check valve, ball valve, safety relief valve and
gauge glass.
• Can be custom congured to meet customer
requirements.
• Stainless steel striking plate standard.
*Flash Separators over 18" diameter,
cleanout will be 2" NPT coupling.
Follow the “Pressure From...” down vertically on the chart above to the “Pressure To...”.
EXAMPLE: 75 PSIG condensate ashed to low pressure heating system at 15 PSIG gives 7.6% condensate ashed into system.
After determining the percent of ash from
the chart to the right, determine the size of
Flash Separator from the chart on the back.
EXAMPLE: Referring back to the chart to
the right, you have a 7.6% ash, if you have
30,000 #/hour condensate at 75 PSIG,
2,280 #/hour steam (30,000 x .076). Locate
30,000 in the left column of the chart on the
back, go across to 2,280 #/hour ash steam
column (3,000). You would use a 56" high x
18" diameter Flash Separator with a 3" draft
and 5" vent.
