TAPPI TIP 0404-39: Dryer surface temperature measurement

Publication Date: Jan 1, 2012
SDO: TAPPI: TAPPI
 DOD Adopted   ANSI Approved Approved

Dryer section performance has a major effect on paper machine productivity and sheet quality. Production rates are frequently limited by drying capacity, which in turn is dependent on heat transfer from the steam in the dryers to the paper. To produce high rates of heat transfer to the sheet, high dryer surface temperatures are necessary. In order to achieve high quality, a uniform temperature is needed across the width of the dryers. Dryer surface temperature and temperature uniformity are therefore critical parameters in evaluating dryer section performance. The information that follows summarizes techniques and procedures that are available for measuring dryer surface temperatures. Suggestions for interpreting data are also included
