YANKEE HOODS

Air and Steam Technologies for Paper Industry

Kappa’s target is to increase speed and production for Yankee Paper Machines, 650°C Hood and 150 m/s blowing air. The Hood increases the Evaporation Rate of Yankee Cylinder up to 60%, meeting Customer’s need.

Technical Information
  • 650°C HT Hoods
  • 150 m/s blowing air velocity
  • Evaporation Rate up to 60% of the total
  • 92% recirculated air
  • Special steel for high temperature
  • Correction of Humidity profile with automatic dampers

Advantages

The High Efficiency Hoods for Yankee Machine are designed to reduce loss of charge inside ducts and to increase, at the same time, performances. The air supply to the blower boxes is barycentric; this means a uniform air distribution over all paper width.

Case study: SHP SLAVOSOVCE (SLOVAKIA)
  • 500°C blowing temperature
  • 120 m/s air velocity on the paper
  • 3 stages heat recovery (burners, room ventilation, water for pulp)
  • Yankee cylinder ø4.000 mm, paper width 3.300 mm
  • Humidity profile control
