Wood drying (also seasoning lumber or wood seasoning) reduces the moisture content of wood before its use. When the drying is done in a kiln, the product is known as kiln-dried timber or lumber, whereas air drying is the more traditional method. There are two main reasons for drying wood:
The board foot or board-foot is a unit of measurement for the volume of lumber in the United States and Canada. It equals the volume of a board that is one foot (30.5 cm) in length, one foot (30.5 cm) in width, and one inch (2.54 cm) in thickness, or exactly 2.359 737 216 liters. [1] Board foot can be abbreviated as FBM (for "foot, board ...
The wood moisture content is above 25% on a dry-weight basis; The environment is sufficiently warm; Oxygen (O 2) is present; Wood with less than 25% moisture (dry weight basis) can remain free of decay for centuries. Similarly, wood submerged in water may not be attacked by fungi if the amount of oxygen is inadequate. Fungi lumber/timber ...
In 2011, Douglas-fir represented 34.2% of US lumber exports, to a total of 1.053 billion board-feet. [ 41 ] [ 13 ] Douglas fir timber is used for timber frame construction and timber trusses using traditional joinery, veneer , and flooring due to its strength, hardness and durability. [ 42 ]
The lumber company complex included 50 mi (80 km) of train track, lumber drying yards, and a planing mill. [7] Before being transported to the drying yards, lumber passed through a dipping station that contained an alkali solution to prevent fungal staining. Carrying capacity of the drying yards was about 45,000,000 board feet (106,000 m 3). [7]
The cord is a unit of measure of dry volume used to measure firewood and pulpwood in the United States and Canada. A cord is the amount of wood that, when "racked and well stowed" (arranged so pieces are aligned, parallel, touching and compact), occupies a volume of 128 cubic feet (3.62 m 3). [1] This corresponds to a well-stacked woodpile 4 ...
The Japanese noborigama kiln is an evolution from anagama design as a multi-chamber kiln where wood is stacked from the front firebox at first, then only through the side-stoking holes with the benefit of having air heated up to 600 °C (1,112 °F) from the front firebox, enabling more efficient firings.
The central furnace was some 6 feet (1.83 m) long, 2 feet 6 inches (760 mm) high and 13 inches (330 mm) internal width. The upper floor was the drying floor, and only some 5 feet (1.52 m) above the ground floor, hops being laid directly on the slatted floor rather than being laid on hessian cloth as was the later practice.
