RECOMMENDED OPERATION OF DRYER SECTION HOOD AIR SYSTEMS

• The purpose of this Technical Information Paper is to provide guidelines for engineers and operators involved in evaluating the effectiveness of paper machine hoods and related air systems.
• A certain amount of understanding about the form and function of the components within the hood system is critical prior to the application of this TIP.
• A dryer section hood is defined as the enclosure that surrounds the dryers. Its' function is threefold:
  • To contain the water released in the drying process.
  • To provide a uniform drying environment by controlling airflows, temperature and humidity, and
  • To reduce the energy requirements for evaporation by reduction of airflow and control of air currents.

It Provides information on:

• Utility.
• Hood Operation.
• Machine Room Ventilation.
• Basement Enclosure.
• Hook Makeup System.

It Benefits:

• Manufacturer.
• Engineers.
• Operations Manager.
• Financer.
• Auditor.
