Abstract:
Many recent studies focus on the research of heat treated biomass in order to replace fossil fuels. To this end, the subject of the present study relates to the enhancement of the thermal energy content of barley straw, through torrefaction. In more detail, the thermal exploitation of barley straw in combined heat and power plants is examined, instead of incineration, through the implementation of an integrated experimental procedure. At the same time, the impact of the torrefaction process parameters, i.e. time and temperature, is also investigated, while further, innovative kinetic models are applied in order to fit the experimental data using the severity factor R0 which combines the effect of temperature and the time of the torrefaction process into a single reaction ordinate. According to our results, this low cost fuel material could be an alternative source of combustion energy, considering also that terrified barley straw can be produced among various other bioenergy products within the biorefinery and the circular economy concept.
