Blowdown Flash Vessel with Heat Recovery - Heat Recovery on Flash (FSHR-F)

Flash Steam Heat Recovery Unit

The EnviroSep Model FSHR-F, Flash Steam Heat Recovery Unit is a manufactured unit featuring a recovery module facilitating flash steam heat extraction from boiler blowdown. The FSHR-F is ideally suited for heating continuous flow of fluid, such as make-up water to boiler feedwater system. The atmospherically vented unit helps recovery and utilize valuable heat generally lost during boiler blowdown. A Shell and Tube Recovery Module with U-tube configuration is used for recovering energy from the flash steam; Plate and Frame Module is optional. The Model FSHR-F is a complete unit including a Carbon Steel Flash Vessel. Non-continuous flow applications may require additional recirculation and/or relief valving. An optional make-up water control valve may be installed upstream of the unit in order for the make-up to be allowed to thermally expand to atmosphere to prevent system damage. Each Unit is custom engineered and designed to meet specific system requirements. All systems are fabricated and welded per ASME Section IX Code and Standards, and are Hydrostatically tested prior to shipment.
