PREPARATION OF WOOD

Once I have my wood, 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°F and 90°F, the wood's moisture

content is above 30 percent, and ample oxygen is available. 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 stove wood 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.
