Flash steam recovery

Over the 20-year life of the equipment, fuel savings are expected to prevent the generation of over 1750t of CO₂. The laundry uses steam for washing, drying and ironing.

FREME works by passing returning condensate through a flash steam separation vessel and passing the separate flash steam and condensate streams through dedicated plate heat exchangers, where they each heat the boiler feed water. This takes place on the high-pressure side of the boiler feed pumps (i.e. downstream), so the system can safely heat the water to over 100˚C without boiling and causing pump cavitation.
