干燥部的性能对纸机生产率和纸张质量有重要影响。生产率通常受到干燥能力的限制，而干燥能力又取决于干燥器中的蒸汽到纸张的热传递。为了向板材产生高传热率，需要较高的干燥器表面温度和与板材的良好热接触。为了获得高质量，需要在干燥器的整个宽度上保持均匀的温度。因此，干燥器表面温度和温度均匀性是评估干燥器部分性能的关键参数。以下信息总结了可用于测量干燥器表面温度的技术和程序。还包括解释数据的建议。

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 and good thermal contact with the sheet are necessary. 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.
