Abstract:
A new methodology for sampling of spruce bark, wood chips biomass, and mixtures hereof, has been introduced at a Norwegian sawmill. The methodology provides a more reliable representation of the operative volumes of biomass and provides better control of the moisture content. In this study it was important to investigate how many representative samples is necessary to yield a result that determines the feed-in biofuel volumes with the required accuracy to lead to a stable heat production; for this purpose we carefully introduced the Theory of Sampling (TOS). Due to the highly heterogeneous nature of this kind of biofuel, a considerable effort in the form of physical sampling is necessary to achieve representative results, and for this reason automated sampling by means of X-ray measurements was introduced for rapid determination of the moisture content. This project contributes to the green transition by highlighting appropriate (TOS-compliant) sampling procedures as well as new on-line technology. In addition, this will benefit the increased trade of biofuel products, which requires correct pricing in terms of estimating the effective energy content.
