METHOD IN DRYING OF PAPER

摘要

A method in consolidation and drying of paper. A wet web (2) is contacted with superheated steam, whose temperature is 200-600 DEG C, for the purpose of reducing, by heat transfer from the superheated steam, the water content of the web (2) by evaporation of a substantial part of the water in the same. The wet web (2) is supported and transported by means of a heat-conductive, gas-impermeable belt (4) whose width is equal to or exceeds the width of the web, and jets of the superheated steam are directed towards the side of the web (2) facing away from the belt (4).
