Definitions

  • the overpressure in the boiler is set to be greater than 1 bar to 8 bar, values between 2 and 4 bar being preferred because the greatest process acceleration results in this area.
  • shorter reaction times can be achieved through higher pressure and temperature values. However, since these are only between 1 and 5 minutes, shortening the reaction time no longer brings about any significant reduction in the total treatment time. The main time saving is achieved by evacuating the goods and by the short fleet ratio.
