Abstract (en)
A plant and method for heat treatment of ligneous material in steam developing from evaporation of water therefrom are provided. Before loading into a heat chamber, the ligneous material (25) is arranged upon a carriage (24) so as to fill the work volume (2) of the heat chamber substantially mirror-symmetrically, close to the outline of the cylindrical inner face of the heat chamber, but without contact between the ligneous material (25) and pipes (6) or inner surface of the heat chamber and advantageously not higher than the uppermost pipe (6). Space between neighboring pieces of the ligneous material (25) being provided. Due to arrangement of pipes (6), conditions for natural convective circulation of the gaseous medium are provided within the heat chamber. A fluid heat-transfer medium flowing through the pipes (6) is used as a heating agent.
