PHYSICAL AND CHEMICAL PROPERTIES OF PINE WOOD CHIPS PRODUCED FROM LOGGING RESIDUES

Keywords: logging residues, biomass, calorific value, ash
Abstract:

The paper presents research results into quantities of branches and tree tops forming logging residues as well as the calorific value, moisture and ash contents of chips burned in a fluidal boiler. The results showed that logging residues make up 17% of the above ground tree biomass, which gives about 52.8 t/ha. The calorific value of the wood chips was 7.8 MJ/kg for fresh material, 12.9 MJ/kg for chips after 4 month storage time and 16.2 MJ/kg after storing the chips for 8 months. The ash from chips burned in a boiler with a fluidised bed contained 62% of silicon dioxide, resulting from the filling role of sand in the fluidal bed. The share of CaO was 6%, MgO – 2.8% and N2O – 0.4%.
