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. ... As pre-heat, for any applicable heating system.

In a pumped condensate return system, the flashing condensate is discharged into a vented tank, from which the flash steam is returned to Deaerator tank/Water tank. The condensate must be pumped from the vented tank to the collecting tank, and then pumped from the collecting tank to the boiler.

Condensate is distilled water, which contains almost no total dissolved solids (TDS). Boilers need to be blown down to reduce their concentration of dissolved solids in the boiler water. Returning more condensate to the feed tank reduces the need for blowdown and thus reduces the energy lost from the boiler.

Condensate is a valuable resource that contains around 25 percent of the heat energy from the original steam. If you feed the boiler with high-temperature condensate you have the potential to maximise boiler output as less energy is required to convert make-up water into steam.
