Sales wood chips

DEFINITION AND PROPERTIES
In order to produce wood chips, woody biomass, with the intention of being burned afterwards, must be chopped. The chipping process is described in more detail on the pre-treatment page.

Because of the chipping process, wood chips are a relatively uniform fuel, which is able to flow and can be fed to a boiler automatically. The average dimension of a wood chip is from 16 to 45mm. For wood chips there are standard sizes, which are defined in the standard mentioned below. The size specification refers to the cross-sections of the holes in a round hole sieve. Because of the high surface area-to-volume ratio, they can be burned efficiently.

Compared to log wood, wood chips have a lower bulk energy density, which leads to a larger space requirement during transport and storage.
