the key parameter that affects both how the chip and sawdust burns and the energy output is the moisture content. A newly felled tree will typically have a 60% moisture content and will be more difficult to burn, with less energy output. Seasoning is usually employed to reduce the moisture content. this is the same process used for the preparation of logs for use as firewood. the lower the moisture content, the greater the energy value.
