Pellets are mostly manufactured from waste products from sawmills and other wood processing industries. The materials used, include ground woodchips and sawdust. No chemical additives are needed, the natural lignin of the wood itself serving as a binder.
How are wood pellets made?
-
Dried wood chip delivered to the plant from the sawmill.
-
The hammer mill prepares the wood chip for the pellet machine, creating fibers of uniform size.
-
The fibre is moistened with steam and rolled in the pellet machine through holes in a die, which form the pellets.
-
The pellets are cooled and double-screened to remove fines.
-
A final vacuuming removes any loose dust.
-
The product is then packaged.
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 2cm 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. It also means that the boiler response time is fast and the technology is controllable without increasing the load on the environment.
