Abstract

This study is concerned with impingement drying of linerboard. The linerboard webs used in the tests were made on a production board machine and on a pilot board machine and sampled after the press section at approximately 45% solids. Impingement drying with hot air, as presented in this paper, offers a new and effective method for drying board, especially at the beginning of a dryer section where delamination is normally a severe problem in multi-cylinder drying. With the new impingement drying technique it is possible to obtain drying rates of 100 kg/m2h and above, which is much higher than with steam heated cylinders. According to the experimental results, the delamination risk during the initial drying stages can be lowered due to the lower web temperature. The observed changes in board quality resulting from changes in air temperature and impingement velocity were small but repeatable.
