Abstract

This paper is devoted to the consideration of mathematical modeling of heating processes occurring in the drying section of paper-making machine. The main attention is paid to the thermal processes issue occurring at the first stage of paper web drying, the heating. An algorithm for calculating the paper temperature change during its passage through drying cylinders and areas of free movement has been developed. The basic equations for calculating temperature of contact and central layers of the paper web are derived. The formulas for calculation auxiliary parameters of the process are given in the paper. The generalization of the obtained data in the resulting formulas form of the convective and contact periods of the paper web heating is executed. Using the statistical criteria of Student and Fisher, the check for the adequacy of the proposed mathematical model suits the actual working process has been made. The developed mathematical model will be used for simulation modeling of automatic control systems of this process.
