Abstract: The invention concerns a method for the recovery of thermal energy from a steam dryer 2 with a closed circulation 2.1 that produces excess steam SS characterized in that the excess steam SS is condensed to an unclean condensate UC in a steam regeneration unit 3 and in that thermal energy in the unclean condensate UC is recovered by being transferred to a district heating medium HW in a heat exchanger 4 for district heating. The invention concerns also a system for the recovery of thermal energy from a steam dryer 2 with a closed circulation 2.1.
