Abstract:
The removal of fine particles such as needles or small pieces of wood and bark by screening might improve storage behaviour of wood chips due to increased pile ventilation and decreased degradation by microbes. Field trials on storage of screened and unscreened wood chips (forest residues, energy roundwood) in large piles (100 m3, each) were performed for 5 month during the summer of 2017. To monitor changes in fuel quality and dry matter losses, a total of 36 balance bags were placed into each wood chip pile. Highest pile temperatures were measured in the unscreened forest residue wood chip pile (63.1 °C). Screening strongly reduced pile temperature and, thus, might reduce the risk of pile self ignition. Best drying (-20.9 w-%) was observed for the screened forest residue chips. Overall, wood chip piles of forest residues showed better drying, but wood chip piles of energy roundwood revealed smaller dry matter losses.
