Here at Pearson Fuels, we recognise the appeal of firewood and why it has remained such a popular fuel despite the abundance of coal throughout the 20th century. After all, affordability and efficiency can be incredibly convincing! In fact, we may be known for our range of high-quality coals, but that doesn’t mean that we aren’t equipped with the necessary firewood knowledge too. After all, our kiln dried logs are one of our most popular products! Read on as we explain how a kiln furnace works…

Why is moisture bad for firewood?

Wood is known as a hygroscopic material which means that it will draw in moisture from the air. In fact, moisture can also be influenced directly by rainwater too. With this said, wood that is used as a source of fuel is difficult to burn when it is saturated with water and this can result in a dim, lack-lister fire output that is expensive to maintain and damages the environment.

What is a kiln?

As a type of large industrial oven, a kiln is used in order to dry firewood and remove excess moisture that can affect the burning of the fuel. In fact, a conventional kiln implements steam through a network of pipes which creates a hot environment for the logs. This moisture is then removed from the kiln by being converted to water vapour and then evaporating as a gas on the outside. With this said, many experts now tend to use dehumidification kilns because they can recycle the heat rather than expel it outside the kiln furnace.

How hot is a kiln?

In order to remove moisture from firewood without drying the logs out, it is important that a kiln is kept at a suitable temperature. After all, firewood that is exposed to high levels of heat will crumble and be deemed unsuitable for residential burning. As a result, most kinks are kept below 115°C.
In order to obtain a high-quality fire-output from firewood, it is important that the moisture content is reduced below 20%. There are a handful of different ways that this can be carried out, such as traditional seasoning over a 9-12-month period, however kiln drying is faster and more effective.
