Abstract

Lignocellulose-containing material in lumps, such as wood chips, is pre-heated and refined in a refiner (8). Steam generated at the refining is utilized for transporting the chips through a blow-line (5) all the way to the refiner (8). During the transport the chips are heated by heat transfer from the transport steam.
