Computing Moisture Content of Wood, Woodbin, Woodworking Software. http://www.woodbin.com

The moisture content of wood is directly related to the humidity and temperature of the surrounding air. The equilibrium moisture content (EMC) occurs when the wood has reached an equilibrium with its environment and is no longer gaining or losing moisture. Here is a calculator for computing the EMC of wood at or below the fiber saturation point (about 30% moisture content) given the temperature and relative humidity.

Moisture Content

Moisture content in wood fuel is calculated as the percentage difference between the wet weight of the wood and the dry weight of the wood. If the percentage is calculated relative to the wet weight, it is called the wet basis moisture content.

Lanny Henson June 4, 2006

This modular stove is built from used metal containers.

It has a center fire burner module, a sunken 8-liter pot module, and an insulated/ chip drying top cap.
The burner and is made from an institutional food can. It takes all the ware and stress from the fire protecting the rest of the stove body.They are easy to build and can act as fuel cartridges to store fuel for quick and easy use.
The burner module, under development, adds secondary combustion air to the top of the burner.
