BLOWDOWN SEPARATOR
BDS SERIES
Safely Separates
Steam Vapor from Boiler Blow-Off Water
The HBC Blowdown Separator is designed to take water from the boiler during blowdown and reduce it to atmospheric pressure for
disposal. The HBC Separator accomplishes this by separating the subsequent flashed steam from the hot water. As the blowdown
enters the vessel, it is forced into a centrifugal pattern by means of a striking plate. The steam is vented to the atmosphere through a
top connection. The HBC Separator is built as per requirements Section VIII of the ASME Code and stamped by the National Board of
Pressure Vessel Inspectors. The Hurst Blowdown Separator provides an economical means of safe boiler blowdown.
The separator includes a structural steel support stand for
mounting to foundation. Options available are after cooler,
manual cooling valve assembly, automatic cooling valve
assembly, and exhaust heads.

HURST BLOWDOWN SEPARATORS are built
to Section VIII, Division 1 of the ASME Code for
250 PSI design pressure.
(200 PSI design pressure with 150# ANSI flanges).
Blowdown separator
design pressure should
be a minimum of 25%
of the boiler maximum
allowable working
pressure (MAWP) as
recommended by the
National Board.
THREADED VENT & DRAIN STANDARD, FLANGED ARE OPTIONAL
