The hood is a critical component of the paper drying system, whether a high-velocity air cap or conventional ventilation hood. A hood survey from PROdry Technology provides essential information to identify deficiencies in the overall drying system and in the hood itself. A thorough set of measurements taken under operating conditions provides the data for a comprehensive thermodynamic analysis of the system by PROdry engineers. This analysis is used to evaluate:

• Drying capacity
  • System potential
  • Loss of drying
  • Optimizing energy consumption
• Combustion efficiency evaluation
  • Burner setup
  • Energy efficiency
  • Safety
• Moisture profile problems
  • Damper problems
  • Plugging of nozzles
• Mechanical condition of dampers, ducts, bellows, fans, and nozzles

• Example 1 - Drying Loss
• Example 2 - Burner Malfunction
