Abstract
This article presents a case study of Simprosys applied to the energy efficiency evaluation of an exisisting fiberboard drying production line. An energy examination of the dryer and the drying system under current operating conditions was performed using Simprosys 2.1 (Simprotek, Cupertino, CA). Detailed parametric studies of the drying system were carried out. Possible improvements for the enegry efficiency of the dryer itself and the drying system are proposed and discussed.
