Kiln Dried Logs

Kiln Dried Logs

Kiln drying involves the introduction of heat to reduce the water content of the firewood. Heat is traditionally provided by gas or electric heating, by steam heat exchangers or via solar power. Most log drying kilns operate at temperatures of up to 110 degrees Celsius, with typical log drying times of 1-2 weeks. A kiln schedule is used to determine the exact time and temperature required to effectively dry the firewood, based on the type of wood involved.

Traditional kilns are constructed of brick masonry or a hollow cement structure and the wood is stacked in chambers to optimise the air flow around the logs and therefore improve drying. Air circulation is critical, to carry evaporated moisture away from the wood and this is often assisted by fans in the kiln. Dehumidification systems are also sometimes used to maintain the humidity of the kiln at a constant level during drying. In dehumidifying kilns, water vapour is condensed off in the dehumidifier and removed as a liquid.

After the kiln drying process is complete, most timbers will hold less than 10% moisture, making them a safe, clean and high energy fuel.

During the kiln drying process, insects and mould are killed off, meaning that kiln dried logs are cleaner, lighter and better burning than air dried firewood. To determine if the kiln drying process has been effective, there are three practical methods of measuring moisture in wood.

Physically weighing the timber before and after drying it and calculating the moisture content.
Using a pin type meter which measures the electrical resistance of the timber.
Using a meter that uses electro-magnetic technology to measure moisture.

Logs which have been kiln dried produce the highest possible heat output when burned due to a much lower moisture content (kiln dried logs have less than 20% moisture, whilst the driest seasoned logs usually still have 30% moisture). The more moisture present in the logs, the more heat energy is wasted in water evaporation when the logs are burned.
