High-temperature initial drying of wood: potential for energy recovery

High-temperature initial drying of wood: potential for energy recovery

Forest Products Journal 30(1): 29-34

Green 1-inch thick boards of (a) cottonwood (Populus deltoides) and (b) sugar maple (Acer saccharum) were initially dried in a prototype jet dryer for 1 h at 300 deg /190 deg F dry/wet-bulb temp. and 250 deg /180 deg F dry/wet-bulb temp. respectively. They were then transferred to a conventional kiln and dried by standard schedules. Some 90% of (a) and 73% of (b) was clear of defects.
