Flash steam and condensate heat recovery system Spirax Compact FREME (Flash Recovery Energy Management Equipment) is an innovative heat recovery system that deliversmajor energy savings by recovering waste heat from a condensate return system and using it to pre-heat boiler feedwater.Heat and water previously lost can be effectively recovered, reducing utility bills, water treatment chemical costsand CO2 emissions. Spirax Compact FREME is proven to be able to achieve energy savings of up to 26%, giving a potential returnon investment within months. Proven energy savings Using condensate returned from the steam distribution system to heat boiler feedwater is an extremely effectiveenergy saving measure. For every 6°C rise in boiler feedwater, 1% is typically knocked off the boiler energy bill. However, many steam systems fail to recover all the heat in returned condensate because: • It would raise the feedtank temperature from the typical 85°C to 90°C to above boiling point, causing cavitation that can damage boiler feed pumps. • Up to half of the recoverable energy in condensate can be lost as flash steam when condensate leaves a pressurised steam system and returns to atmospheric pressure
