10 hilariously insightful foreign words. Kiln dried lumber is lumber that has been heated in a kiln so that it has a low moisture content. When the drying process is complete, the lumber usually has a moisture content of between 6% and 8%, making it significantly dryer than green lumber or air dried lumber.n the case of kiln dried lumber, the wood is dried in giant kilns with carefully controlled temperature and humidity levels. The goal is to get the boards to dry quickly and evenly, and to prevent warping that could render the wood unusable.
Wood is air-dried or dried in a purpose built oven (kiln). Usually the wood is sawed before drying, but sometimes the log is dried whole. Case hardening describes lumber or timber that has been dried too rapidly.Wood initially dries from the shell (surface), shrinking the shell and putting the core under compression. Wood burning: when wood is burned, it is usually best to dry it first. 2  Damage from shrinkage is not a problem here, and the drying may proceed more rapidly than in the case of drying for woodworking purposes. 3  Moisture affects the burning process, with unburnt hydrocarbons going up the chimney.
