摘要

Method for utilization of waste heat in desiccation and/or heat treatment of timber, in which desiccation/heat treatment the timber (0) is treated in a treatment space (6), such as a drying chamber. In the method, steam/combustion gas (7) generated in the combustion of a fuel used for heating is supplied into the treatment space (6) and at least a proportion of the steam/combustion gas is scrubbed/humidified before being passed into the treatment space (6), or steam/gas generated in the treatment space e.g. during heat treatment is circulated back into the treatment space.
