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.
Limestone is fed into the upper or back end of the kiln, while fuel and combustion air are fired into the lower or âfront endâ of the kiln. The limestone is heated as it moves down the kiln toward the lower end. As the preheated limestone moves through the kiln, it is âcalcinedâ into lime. The lime is discharged from the kiln into a cooler where it is used to preheat the combustion air. Lime can either be sold as is or crushed to make hydrated lime.
