| 摘要 |
<p>The invention relates to a wood chip drying system for drying wood chip (18) comprising a furnace (12), a drier (16) for the wood chip (18) and a recirculation apparatus (56) for the recirculation of exhaust vapors (34) into the drier (16), wherein the recirculation apparatus (56) has an exhaust vapor heater (42), and wherein the wood chip drying system (10) is designed to reduce organic compounds present in the exhaust vapor (34) prior to the recirculation into the drier (16). The exhaust vapor heater (42) comprises a regenerative and/or catalytic heat exchanger which is arranged downstream after the drier (16) and which is designed so as to heat up the exhaust vapor (34) to a temperature which is high enough to oxidize at least a majority of particles present in the exhaust vapor (34).</p> |
