Abstract: Operation of the furnace-type lumber dry kiln built at the Forest Products Laboratory is essentially the same as that of any conventional steam-heated kiln. Three factors govern the drying of lumber in this type, as in any dry kiln; the temperature, relative humidity, and circulation of the air in the kiln. In the furnace-type kiln, the temperature and relative humidity of the air are under good control and a constant uniform air circulation is provided. Either green or air-dried lumber can be dried in this kiln by following the standard kiln schedules in general use throughout the country. This kiln differs from the conventional steam-heated compartment kiln in the methods used to supply heat and maintain the relative humidity. The air-circulation system is a typical internal-fan, cross-circulation system.
