ABSTRACT

ABSTRACT: In paper industry, dryer section of paper machine consumes large amount of energy. It also leads in terms of capital investment as compared with other sections and most of the paper properties are influenced by dryer section, so any improvement in dryer section of paper machine can significantly reduce cost as well as improve paper quality. This paper deals with study of the pocket ventilation in the dryer section of the paper machine. Also it shows the various factors which influence the paper drying process. In the conventional paper machine, the reason for the uneven drying of paper was the uneven pocket air humidity distribution along the cross direction of paper web. This problem can be overcome by improving the pocket ventilation system in the dryer section of the paper machine. This improvement in the pocket ventilation would increase the drying rate of paper web which ultimately reduce the operating cost and energy consumption. Improved pocket ventilation also helps to maintain the uniform humidity profile.
