Abstract
A method and an equipment for regulation of the initial part of the dryer section in a paper machine. Moisture is removed from the paper web in the press section (10) and the paper web is dried in the dryer section (R). The paper web is dried against heated faces of drying cylinders (20). The surface temperatures of the first drying cylinders (20) in the dryer section (R) are measured. The dry solids content/moisture content of the paper web (W) and the temperature of the paper web (W) before said first drying cylinders (20) are measured. In view of producing the desired running situation, based on the measurement results obtained, the surface temperatures of said first drying cylinders (20) and/or the dry solids content/moisture content and/or the temperature of the paper web (W) before said first drying cylinders (20) is/are regulated.
