<p>A description is given of a method for drying wood, wherein the wood is subjected in a pre-drying chamber (1) to heated incoming air (11) sucked in over a cross-flow heat exchanger (8) and is subjected in a main drying chamber (2) to recirculated air (3), passed in circulation (6) over a heating register (5), from which a partial stream is separated as extracted air (7) and is replaced by incoming air, which is preheated with the aid of the extracted air (7) in a cross-flow heat exchanger (8). To allow the waste heat to be used advantageously, it is proposed that a shared cross-flow heat exchanger (8) arranged upstream of the pre-drying chamber (1) and the main drying chamber (2) is subjected to the extracted air (7) separated from the recirculated air (3), and that the incoming air (11) heated in this cross-flow heat exchanger (8) is used on the one hand to pre-dry the wood in the pre-drying chamber (1) and on the other hand to supplement the extracted air (7) extracted from the recirculated air (3) of the main drying chamber (2).</p> |
