FV

Flash Vessel

Description

The Spirax Sarco FV flash vessel is designed and constructed to ASME VIII

DIV 1 2004 + ADD06. The design is free-draining which is essential in boiler

blowdown applications.

Applications

These vessels are particularly suited to boiler blowdown heat recovery systems

where efficient separation of the flash steam from the blowdown is essential

to prevent contamination of the boiler feedtank and / or heat transfer surfaces.

Spirax Sarco flash vessels are equally suited to condensate flash steam

applications.

Principal features:

-

Designed and constructed in compliance with the European Pressure

Equipment Regulations 2014/68/EU.

-

Low separation velocity to produce drier steam.

-

Free-draining.

Sizes and pipe connections

Connections available as standard:

Screwed connections to BS 21 taper.

Flanged connections to EN 1092 PN16.

Note: Vessels are available flanged to ASME B16.5 Class 150 or 300, or

screwed NPT.

Limiting conditions

Maximum design conditions (body) are 14 bar g @ 198 °C (saturation temperature of steam).

Minimum design (operating) temperature

Model FV15 and FV18 shown

-10 °C

Cold hydraulic test pressure in accordance with European Pressure Equipment Directive 2014/68/EU.

Note : Maximum design Pressure and Temperature can be further limited, lower than that stated on the nameplate depending on the

chosen flange rating of the system.

PN16

13.3 bar g @ 198 °C

Class A150

13.8 bar g @ 198 °C

Note: These vessels will withstand full vacuum conditions.
