Oak is known for its long, slow burns. The fire from well seasoned Oak in your wood stove can't be beat! Oak burns clean if you have seasoned it properly. Burning green Oak firewood will result in a lot of smoke and creosote build up.
Burning a recently cut live tree's wood, referred to as "green wood," is not the best use of the resource or safe in a home. Green wood's high moisture content makes the wood difficult to burn. The moisture also results in excessive smoke, causing green wood to be a poor choice for indoor furnaces or wood stoves.
Recently cut, or green, wood retains water and is troublesome to burn. White oak especially must be seasoned prior to being burned. Make it possible for it to dry out for a minimum of one full year before putting to use as firewood.
While you may not always have the luxury of choosing what wood to use, some types of seasoned firewood will provide better results. For example, oak is a very good choice for wood burning furnaces, because it's dense and it burns hot. But you should season oak for at least a year before using it.
Even today, though, most of the chemicals used for this wood-preservation method are toxic to humans. If you burn pressure-treated wood in your fireplace, these chemicals will be released into the same air that you and your family breathe.
Evergreen trees are softwoods, so avoid buying firewood that comes from pines, firs or cypress trees. Freshly cut or unseasoned wood. Wood that has just been cut from the tree is still loaded with natural moisture. This makes the wood more difficult to burn.
On average 25mm of oak dries per year. Seasoning can take anything between three to ten years depending on the thickness of the oak. The moisture content of air-dried oak is around 20-30% or more.
Curing Oak Firewood By Air Drying Takes About 6 to 24 Months
If your oak firewood is still green and has a high moisture content of about 70% to 80%, allowing it to air dry for six months to two years should result in a moisture content of 20% or lower.
Seasoned wood will be darker in color than green wood, and may be cracking at the ends. Seasoned wood can also lighter in weight and the bark can be peeled off more easily than unseasoned wood. A moisture meter will be able to provide an accurate reading of whether firewood is fully seasoned or not.
The best-known firewoods are white and red oak trees. The wood from these oak trees is prized for its strength and density, and that density makes it one of the best at producing heat.
Oak Trees Provide Dry Firewood
When both types of oak trees are compared to other trees out there, Red Oak and White Oak are the best firewoods. Both White and Red Oak Trees will provide dry firewood, which is ideal for fire burning. But – oak trees are definitely not in ideal conditions when it's cut down right away.
White oak takes 8 to 10 months. After that, it needs to be put in a kiln to dry it below 10%. Your flooring will need to be 8% or even a bit less. However, we get good air drying conditions throughout the year here whereas in Ohio if you get a lot of snow, drying will slow down considerably in the winter.
Green wood is very wet with a lot of sap and moisture content, so much so that nearly 50% of the weight of a stick of green wood can be water alone. Due to its high-water content, green wood is one of the worth things that you can burn in your fireplace.
When a living tree is cut down, the timber needs to age or "season" for a minimum of six to nine months before burning. Freshly cut wood, called green wood, is loaded with sap (mostly water) and needs to dry out first.
To get green wood to less than 20% moisture takes at least six months. Freshly cut wood will have bound and unbound moisture. The latter is released fairly easily and can get the wood down to 25 to 30% moisture content. Bound moisture, on the other hand, takes much longer to evaporate.
All you need to do is set up a decent dehumidifier beside the stack of wood to be dried, let it run, and it will suck the moisture right out of the wood. This can speed up the drying time from months or weeks to just a few days. Even better is if you add an air fan into the mix to produce some extra airflow.
Back to the question at hand: Yes, oak trees make excellent firewood. One of the many reasons why oak is ideal for firewood is because it's easy to split. While there are hundreds of species, all oak trees have a straight grain that makes them easy to split.
Green oak is often used as a constructional timber as beams. The timber is fresh cut from the log and as such will be subject to moisture movement as the wood naturally dries out. You'll need to take this into account when using the timber.
Green oak is used for oak framed buildings because it is strong, durable and easier than dried oak to work with, as well as less expensive. 2. Green oak is much easier than seasoned oak to cut and shape precisely, even when power tools are taken to seasoned oak. 3.
Both Seasoned Oak and Green Oak are from the same Oak tree (it is not a different species). The only difference is the level of moisture held in the specific piece of timber which is determined by how long the tree has been felled and the circumstances it has been subjected to.
Hardwoods such as maple, oak, ash, birch, and most fruit trees are the best burning woods that will give you a hotter and longer burn time. These woods have the least pitch and sap and are generally cleaner to handle.
Yes, it is possible that burning rotten wood can make you sick. Burning rotten wood produces a nasty odor and releases fungus, mold, mildew, and bacteria. These are very bad for your respiratory tract when inhaled. You also should never burn treated wood, including wood that was treated with paint, glues, or stains.
Those woods are usually the more exotic tropical hardwoods, such as rosewood, padauk, and teak, but sassafras (a relatively common found wood) can cause breathing problems, nausea, or even cancer.
