  • Introduction to Condensate Recovery

    2020-1-16 · 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.

  • Condensate Recovery: Vented vs. Pressurized Systems

    2020-1-15 · Since vented recovery systems are typically less costly to design and install, these will typically be used in instances where the return on investment is deemed too low to adopt a pressurized recovery system, for instance, in systems that use lower pressure steam.
