2. Firewood - Wikipedia

   en.wikipedia.org/wiki/Firewood

   The moisture content of firewood determines how it burns and how much heat is released. Unseasoned (green) wood moisture content varies by the species; green wood may weigh 70 to 100 percent more than seasoned wood due to water content. Typically, seasoned (dry) wood has 20% or less moisture content. Use of the lower heating value is advised as ...

3. Green wood - Wikipedia

   en.wikipedia.org/wiki/Green_wood

   Green wood is considered to have 100% moisture content relative to air-dried or seasoned wood, which is considered to be 20%. Energy density charts for wood fuels tend to use air dried wood as their reference, thus oven dried or 0% moisture content can reflect 103.4% energy content.

4. Wood drying - Wikipedia

   en.wikipedia.org/wiki/Wood_drying

   The chemical potential of sorbed water is a function of wood moisture content. Therefore, a gradient of wood moisture content (between surface and centre), or more specifically of water activity, is accompanied by a gradient of chemical potential under isothermal conditions. Moisture will redistribute itself throughout the wood until its ...

5. Wood-burning stove - Wikipedia

   en.wikipedia.org/wiki/Wood-burning_stove

   Firewood with a moisture content below 20 per cent by weight can burn efficiently. This is the "free" moisture content absorbed in the wood fibers, and does not include the chemically-bound hydrogen and oxygen content. Moisture content can be reduced by outdoor air-drying ("seasoning"), for a period of several months in summer weather.

6. Wood fuel - Wikipedia

   en.wikipedia.org/wiki/Wood_fuel

   The Sustainable Energy Development Office (SEDO), part of the Government of Western Australia states that the energy content of wood is 16.2 megajoules per kilogram (4.5 kWh/kg). [6] According to The Bioenergy Knowledge Centre, the energy content of wood is more closely related to its moisture content than its species. The energy content ...

7. Equilibrium moisture content - Wikipedia

   en.wikipedia.org/wiki/Equilibrium_moisture_content

   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 longer changes in time. This moisture content is the EMC of the wood for that temperature and relative humidity.
