  • Publication number: 20110305897
    Abstract: A wood chip drying system for drying wood chip includes a furnace, a drier for the wood chip and a recirculation apparatus for the recirculation of exhaust vapors into their drier. The recirculation apparatus has an exhaust vapor heater, and the wood chip drying system is designated to reduce organic compounds present in the exhaust vapor prior to the recirculation into the drier. The exhaust vapor heater includes a regenerative and/or catalytic heat exchanger which is arranged downstream after the drier and which is designated so as to heat up the exhaust vapor to a temperature which is high enough to oxidize at least a majority of particles present in the exhaust vapor.
