Abstract [en]

The current investigation focused on obtaining experimental results on properties of different woody and oily biomasses during lab-scale storage. During large-scale storage of vegetable oils, biodiesel and woody biomasses, physical, biological and chemical processes lead to deterioration of the fuel, self-heating and in some cases to self-ignition. The heat released from the different biomass samples was measured by isothermal calorimetry, with the purpose to assess the biomass suitability for storage. The highest thermal output came from the boiled linseed oil, but also from olive oil. Wood pellets give rise to different levels of thermal output during storage and the levels depend on the moisture content, ambient gas media but not the resin content. The total energy release, as well as the peak value for the thermal power development in the individual ampoules, was limited by the amount of oxygen present. In spite of this, chemical heat release rates well exceeding 50 W/tonne were registered already at a sample temperature of 50 °C. The results are intended to be useful when planning for the large-scale use of different biomasses, leading to the need of storage. By measuring the heat released from different biomass samples, the biomass suitability for storage can be assessed.
