Title:
WOOD DRYING METHOD
Document Type and Number:
WIPO Patent Application WO/2001/066322
Kind Code:
A1
Abstract:
A wood drying method comprising the steps of charging a ligneous fuel, such as waste wood, into a combustion chamber (4a) disposed in the lower region of a combustion gas generating furnace (4) to burn the same, introducing the high temperature combustion gases generated by this combustion into the upper region of a drying chamber (1) in which undried wood has been stored, whereby the wood is heat-dried by the combustion gases, wherein the wood is efficiently dried in a short time by heat-drying the same while maintaining the combustion gases in the drying chamber atmosphere at high concentration. Further, the wood is efficiently dried in a shorter time by sealing the drying chamber to maintain the pressure of the drying chamber atmosphere at high values.
