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: Woodworking
To reduce the drying time to a number of days from the normal one to three years, an external heating source such as a kiln or oven can be used. The process of kiln or oven drying firewood was invented by Anthony Cutara, for which a successful US patent was filed in 1983. [22]
The burning of wood results in about 6–10% ashes on average. [2] The residue ash of 0.43 and 1.82 percent of the original mass of burned wood (assuming dry basis, meaning that H 2 O is driven off) is produced for certain woods if it is pyrolized until all volatiles disappear and it is burned at 350 °C (662 °F) for 8 hours.

A cord of wood. 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]

where m is the mass of the wood (with moisture) and is the oven-dry mass of wood (i.e. no moisture). [3] If the wood is placed in an environment at a particular temperature and relative humidity, its moisture content will generally begin to change in time, until it is finally in equilibrium with its surroundings, and the moisture content no ...
