If 1 th of steam is supplied to equipment for a heating process, then the same amount of condensate (1 th) needs to be discharged from the equipment. Condensate recovery is a process to reuse the water and sensible heat contained in the discharged condensate. Recovering condensate instead of throwing it away can lead to significant savings of energy, chemical treatment and make-up water.
Condensate can be reused in many different ways, for example
As heated feedwater, by sending hot condensate back to the boiler’s deaerator
As pre-heat, for any applicable heating system
As steam, by reusing flash steam
As hot water, for cleaning equipment or other cleaning applications
