Why is there such a difference in fuel consumption between kilns?
Firstly, it is necessary to understand a little about the moisture carrying capacity of air. A cubic metre of air at 20 deg. centigrade and 100% relative humidity will hold around 14 grams of water. If you were to heat the same cubic metre of air up to 70 deg. centigrade it would be holding around 400 grams of water at 100% relative humidity. It can be seen from these figures that the moisture carrying capacity of air varies greatly dependent upon temperature and relative humidity. Some kilns are poorly designed and the hot air is simply passed into the drying compartment over the logs and the same volume of air is then extracted and or vented. There is no control over the amount of moisture that the air is carrying. Our kilns are manufactured to work on a completely different principle and use an automatic relative humidity / moisture control system. The air in the drying compartment is circulated around the logs until it has achieved the correct relative humidity and is fully moisture laden. Once these conditions are met, the moisture laden air is vented and replaced by fresh dry air and the process is repeated.
