Modeling and Simulation of Multi-Cylinder Paper Drying Processes

초록

A dynamic model describing the behavior of a multi-cylinder paper drying processes is developed based on the mass and heat balances around drying cylinders. The multi-cylinder model is an expansion of a single cylinder model coupled with the behavior of the paper web and the felt. The balance equations consist of sets of differential equations describing heat and mass transfer around the canvas, the web and the drying cylinders. The values for the cylinder temperatures and moisture contents are estimated and compared with operating data. In order to obtain further information for energy consumption generation of entropy at each drying cylinder is investigated based on the model developed.
