Abstract

The present invention relates to a method of heating timber to a predetermined temperature in a preheating phase of a timber drying process. The timber is placed in an at least substantially closed chamber in which there is sustained an atmosphere that contains aqueous steam and has a wet temperature and a dry temperature. The method includes raising the wet and the dry temperature of the atmosphere. The method is characterised by raising the dry temperature in keeping with a rise in the wet temperature.
