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.
The energy content is about 4-4.2 kcal/kg and moisture content is typically less than 10%. The size of pellets is generally kept to be about 6 mm diameter and 25 mm length in the form of a cylinder; though larger cylinder or briquette forms are not uncommon. It is much cheaper than similar energy-pellets and can be compacted/manufactured from ...
Consumer grade hydraulic log splitters were developed to be powered by electricity, gasoline, or PTO of farm tractors. In 1987 the US Department of Agriculture published a method for producing kiln dried firewood, on the basis that better heat output and increased combustion efficiency can be achieved with logs containing lower moisture content ...
The energy content of a measure of wood depends on the tree species. [19] For example, it can range from 15.5 to 32 million British thermal units per cord (4.5 to 9.3 GJ/m 3). [20] The higher the moisture content, the more energy that must be used to evaporate (boil) the water in the wood before it will burn.
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.
Burning a wood briquette is far more efficient than burning firewood. Moisture content of a briquette can be as low as 4%, whereas green firewood may be as high as 65%. For example, parameters of fuel briquettes made by extrusion from sawdust in Ukraine:
This is the temperature of the burning wood itself, not of the smoking environment, which uses much lower temperatures. Woods that are high in lignin content tend to burn hot; to keep them smoldering requires restricted oxygen supplies or a high moisture content. When smoking using wood chips or chunks, the combustion temperature is often ...
A process of thermal modification of pressurized wood with a medium moisture content was described in a paper by Burmester in 1973. [3] Today there are five different thermal modification processes. Finland produced Thermowood also known as Premium wood. France uses the Les Bois Perdure Retification process, the Netherlands uses the Plato ...
