摘要： A method and an arrangement for utilizing energy of an apparatus for drying a fibre web. The drying apparatus comprises two endless bands (1, 2) that are impermeable to air and that have a good thermal conductivity. A fibre web (5) runs between the bands (1, 2) with at least one felt or wire (3, 4). The metal band in contact with the fibre web (5) is heated with a pressure chamber (9) containing a pressure medium that is steam. Correspondingly, the metal band in contact with the felt or wire (3, 4) is cooled. The pressure chamber (9) is sealed against the first band (1) with a seal (9a). In association with the pressure chamber (9) there is a steam recovery chamber (18), where steam and condensate that escape from between the seal (9a) and the first band (1) can be recovered. The steam recovered from the steam recovery chamber (18) is supplied for further use with a means according to the arrangement.

摘要： An apparatus for drying and smoothing a fibre web (5) between two tight bands (1, 2) that move in parallel and turn around turning rolls (6a, 6b, 7a, 7b), the first band (1) being heated with hot steam and the second band (2) being cooled with water, and the fibre web (5) being conducted through the drying zone that the bands (1, 2) define together with at least one felt or wire (3, 4) such that the fibre web (5) is in contact with the surface of the first, heated band (1) and that the felt or wire (3, 4) is between the fibre web (5) and the second, cooled band (2). In the invention, the fibre web (5) is smoothed such that the press means located in the vicinity of the first turning rolls (6a, 7a) in the travel direction of the fibre web (5) apply to it a pressure that is essentially higher than the pressure in the other parts of te drying zone. The pressure that the fibre web is subjected to in the drying zone is sufficiently high to prevent the fibre web from shrinking in the longitudinal and transverse directions, and yet sufficiently low to prevent the fibre web from becoming essentially thinner.
