Abstract (en)

[origin: WO2010020485A1] The invention relates to a method and to a device for drying a paper web. In order to improve the efficiency in drying a paper web, a method or a device is proposed wherein an alternating electromagnetic field (3) is produced by at least one transmitter (2, 6) and the paper web (1) is lead through the alternating field at least once. The energy efficiency is very high in the proposed method because no energy-absorbing medium is heated except the water in the paper.
