Introduction to Condensate Recovery | Spirax Sarco

Part 2 - Determine the water cost. Water is sold by volume and the density of water at normal ambient temperature is about 1000 kg /m3. The total amount of water required in one year replacing non-returned condensate is therefore: If water costs are £0.61 per m³ the annual water cost is: Annual water cost = 84000 m3/ year x £0.61/m3 = £51 240

Introduction to Condensate Recovery | TLV - A Steam ...

By absorbing this Latent Heat water becomes steam and by releasing it steam reverts to high temperature water (condensate). When steam condenses at the threshold or instant of phase change the condensate temperature is the same as steam because only the latent heat has been lost and the full amount of sensible heat remains.

Steam condensate and waste water recycling process ...

This steam can be condensed in a flash condenser and the heat contained in this steam can be recovered by running waste water through the flash condenser where it will intimately mix with the condensing steam and thus retain its heat value in the mixture. The condensate-water mixture is then returned to the flash tank.
