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