Wood pellets can be used to produce heat in a specially designed stove or boiler. In addition, some existing solid fuel and oil boilers can be converted to make use of wood pellets. Pellets are mostly manufactured from waste products from sawmills and other wood processing industries. The materials used include ground woodchips, sawdust and bark. No chemical additives are used. Due to it pellets are ecologically clean fuel.
Due to their low moisture content (about 6% to 10%) pellets have a high energy content, similar to high quality coal. Only minor energy losses are experienced due to the need to burn off the moisture content.
Being manufactured to a consistent size (usually about 2 – 3 cm long with a diameter of 6 to 8mm for domestic heating), low moisture content and high density means that wood pellets can be used in automatic clean-burn heating appliances. This and the fact that they are clean and easy to handle make them particularly suitable for domestic use. Being compressed also means that they take up less room than other forms of wood fuel.
