DRYER SURFACE TEMPERATURE MEASUREMENT

• Dryer section performance has a major effect on paper machine productivity and sheet quality. Production rates are frequently limited by drying capacity, which is dependent on heat transfer from the steam in the dryers to the paper.
• The information that follows summarizes techniques and procedures that are available for measuring dryer surface  temperatures. Suggestions for interpreting the data are also included.
• The surface temperature of a dryer is a good indicator of performance. The difference between the temperature of the surface and the saturation temperature of supply steam is an indication of heat transfer efficiency from the steam, through condensate in the dryer, and through the cast iron dryer shell.

It Provides information on:

• Analysis of dryer performance.
• Dryer temperature surveys.
• Selection of instrumentation.
• Infrared thermography.
• Interpretation of data.
• Instrument suppliers.

Who it Benefits:

• Engineers.
• Auditors.
• Technical Manager.
• Production Manager.
