CHAPTER 21: EVAPORATION – PRINCIPLES, TYPES OF .

A single-effect evaporator as shown in Fig.1 is wasteful of energy since the latent heat of the vapor leaving is not used but is discarded. However, much of this latent heat can be recovered and reused by employing multipleeffect evaporators. A simplified diagram of a - forward-feed tripleeffect evaporation sys- tem is shown in Fig.2.
