Energysaving in drying processes

ENERGY SAVING TECHNOLOGIES FOR INDUSTRIAL LAUNDRY DRYERS

PRESENT SITUATION

  • Using way to high air volumes (air which had to be heated up expensively)
  • Uncontrolled, constant air flow (volume) throughout the whole drying process
  • Highly deviating temperatures with recurring overheating
  • Damaging of the laundry through excessive heat

>> High energy saving potential

Unregulated drying processRed = burner capacity, Yellow = temperature on the laundry, Green = exhaust air temperature, Blue = incoming air temperature

Red = burner capacity, Yellow = temperature on the laundry
Green = exhaust air temperature, Blue = incoming air temperature

Consequences of an unregulated drying process

  • Inefficient evaporation due to the short dwell time of the hot air in the dryer.
  • Not optimized utilization of the produced energy.
  • The energy is wasted and literally blown out with the exhaust air.
  • Unregulated drying process
  • High costs of primary energy (gas, oil electricity) compared to the outcome/benefit
  • Shutdowns of the gas burner

>> Waste of energy / high production costs
