METHOD AND ARRANGEMENT FOR CONTROLLING THE DRYING OF A COATED OR SURFACE-SIZED FIBROUS WEB

摘要

The invention relates to method for drying a coated or surface-sized fibrous web (W), in which method the fibrous web is coated or surface-sized and after the coating or surface-sizing the fibrous web is dried in a drying line (1) comprising two or more drying units (6). In the method, the final moisture content of the web (W) being dried is measured after (16) the drying line (1), the temperature (T<SUB>1</SUB>) of the web (W) being dried is measured in connection (8) with each drying unit (6) respectively and the drying capacity of each drying unit (6) is adjusted on the basis of the difference between the measured temperature (T<SUB>1</SUB>) and the set value (T<SUB>0</SUB>) of the maximum temperature set for the drying unit in question to control the temperature of the web (W). The invention also relates to an arrangement for implementing the method.
