Wood chips drying plant for drying wood chips and method for drying wood chips

摘要

The chip drying system (10) has a drier (16) for drying a wood chip (18). A recirculation apparatus (56) includes an exhaust vapor heater (42) and recalculates exhaust vapors (34) into the drier. The exhaust vapor heater is provided with a regenerative and/or catalytic heat exchanger, which is arranged downstream behind the drier. The regenerative and/or catalytic heat exchanger heats up the exhaust vapors to a temperature, which is high enough to oxidize the majority of particles present in the exhaust vapors. Independent claims are also included for the following: (1) a method for drying a wood chip (2) a method for producing a derived timber plate.
