METHOD AND DEVICE FOR TREATING STEAM IN A FIBER REFINING PROCESS

摘要

According to the disclosed method, steam generated in the defibration of mechanical pulp, which steam is used for transfer of the fibers from the defibrator to a drying process, is separated from the fiber steam whereby its energy content may be utilized. Preferably this heat energy is used to heat the air supplied to the drying process. Simultaneously, the volatile organic compounds contained in the steam are prevented from entering the environment.
