A. Low Moisture Content. One of the most significant benefits of kiln-dried firewood is its low moisture content. The drying process removes excess moisture, resulting in wood with moisture levels well below the 20% threshold recommended for efficient burning. Low moisture content means the wood ignites easily, burns cleaner, …

Kiln drying involves using controlled heat and airflow to reduce the moisture content of the wood. To kiln dry wood at home, you will need a kiln or a well-insulated space with good temperature and humidity control. Depending on the size and type of wood, the drying process can take several weeks or even months.

In the subsequent half century, efficient dry process kilns have almost completely displaced slurry-fed kilns. The pioneering was done by Blue Circle, who had eight dry process kilns in operation before the start-up of Tunnel's Padeswood A3 in 1966. The types of dry process kilns fall roughly into four categories: Long dry kilns. Lepol kilns.
