Once I have my wood at home, how do I prepare it for burning?
The wood must be cut to length to suit the firebox of the stove, furnace, or fireplace in which it is to be burned. An 8' log may
be cut into four, six or eight pieces, depending on the desired length. Splitting the wood greatly facilitates drying and reduces
the wood to a more manageable size.
How much moisture is contained in wood?
Many softwoods have a moisture content in the vicinity of 55 percent when they are freshly cut. The popular hardwoods have
moisture contents of about 45 percent. Air dried wood has a moisture content of about 15 percent and kiln dried wood may
have a moisture content of less than 10 percent when it is fresh from the kiln.
What causes wood to rot?
When wood is cut, it is very susceptible to the growth of fungi, which converts the wood to water, carbon dioxide, and heat, just
as does a fire. This rotting decreases the wood's energy. The fungi are most productive when three conditions are met: the
temperature is between 60
Thus, wood does not rot appreciably when it is dry, in the winter, or when it is submerged in the water, but it should not be
allowed to lie on the ground during the summer.
How can rotting be prevented?
When the wood has been cut into stovewood lengths, and split, it should be piled outside during the months of June, July, and
August. Two poles should be placed on the ground to serve as rails to keep the firewood off the moist ground and the wood
should be piled up in such a way that it is well exposed to the sun and the wind. The moisture content of the wood will drop
until it reaches equilibrium with the ambient weather conditions. When the relative humidity is 60 percent, the equilibrium
moisture content is about 11 percent. When the wood has reached this equilibrium moisture content, it is said to be "air dried."
Around mid August, it should be placed under cover so that it will not reabsorb moisture from the rain and snow before it is
used.
Why this concern about allowing the wood to dry?
