Energy saving in industrial drying plants by partial recovery of the latent hat of the exhaust air

摘要

Energy saving in industrial drying by recovering part of the latent heat of the vapor exiting the drier is considered in this paper. this heat recovery is accomplished through two-stage heat exchanger system, wherein the first stage brings the primary circuit to vapor saturation conditions, while the second stage acts as a condenser. Optimal heat recovery is assured by intelligent, fully automated process control.
