- Common ash (Fraxinus excelsior L.) wood was heat treated in an oven at the temperatures of 180°C, and 200°C under atmospheric pressure in the presence of air for 3, 6, 9, 12 hours, and the changes in higher heating value (HHV) of wood were studied. For untreated ash wood the value 19.51 MJ·kg-1 was determined. Thermal treatment considerably increased the HHV of wood. The highest value was measured in sample that was thermally treated for 6 h at the temperature of 200°C. In this sample the value 20.78 MJ·kg-1 was determined. Changes in HHV are a consequence of chemical changes in wood during treatment. Strong positive correlation between HHV and the ratio of the sum of lignin and extractives content to holocellulose content was observed.
