Abstract:
In this study a model for the drying process in paper production plants was developed based on the mass and heat balances
around drying cycles. Relationships for the heat transfer coefficients between the web and the air as well as between the
drying cylinder and the web were extracted from the closed-loop plant operation data. It was found that the heat transfer
coefficients could be represented effectively in terms of moisture content, basis weight and reel velocity. The effectiveness
of the proposed model was illustrated through numerical simulations. From the comparison with the operation data, the proposed
model represents the paper plant being considered with sufficient accuracy.
