METHOD IN DRYING OF PAPER

摘要

A method in consolidation and drying of paper. A wet web (2) is contacted wi th superheated steam, whose temperature is 200-600 ~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. T he 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).
