ABSTRACT:
A method and an arrangement for utilizing condensation water 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 is cooled. Water that has evaporated from the fibre web (5) and then condensed is gathered from the wire (4) and this condensate is made suitable for use in a power station by means of the removal of solid matter, so that the condensate can be utilized.
