class="card-text"><strong>Abstract:</strong></p> <p>Worldwide interests for the renewable energy are increasing due to environmental and climate changes from traditional petroleum related energy sources. To account for these social needs, ligneous biomass energy is considered as one of the environmentally friend energy solutions. The wood torrefaction process is a feasible method to improve the properties of the biomass fuel and makes the wood have low moisture, lower smoke emission and increased heating value. In this work, therefore, the moisture evaporation model which largely affects energy efficiency of ligneous biomass through moisture contents and heating value relative to its weight is studied with numerical modeling approach by analyzing the effects of torrefaction furnace temperature. The results show that the temperature and moisture fraction of wood decrease by increasing the furnace temperature. When the torrefaction temperature is lower than 423K, there were little changes of the moisture fraction in the wood. Also, it can be found that charcoal is produced more slowly when the torrefaction temperature is lower than 573K.</p> <iframe src="https://publications.waset.org/16863.pdf" style="width:100%; height:400px;" frameborder="0"></iframe> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Modeling" title="Modeling">Modeling</a>, <a href="https://publications.waset.org/search?q=Torrefaction" title=" Torrefaction"> Torrefaction</a>, <a href="https://publications.waset.org/search?q=Biomass" title=" Biomass"> Biomass</a>, <a href="https://publications.waset.org/search?q=Moisture%20Fraction" title=" Moisture Fraction"> Moisture Fraction</a>, <a href="https://publications.waset.org/search?q=Charcoal." title=" Charcoal."> Charcoal.</a> </p> <p class="card-text"><strong>Digital Object Identifier (DOI):</strong> <a href="https://doi.org/10.5281/zenodo.1087980" target="_blank">doi.org/10.5281/zenodo.1087980</a> </p> <a href="https://publications.waset.org/16863/modeling-moisture-and-density-behaviors-of-wood-in-biomass-torrefaction-environments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/16863/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/16863/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/16863/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/16863/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/16863/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/16863/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/16863/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/16863/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/16863/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/16863/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/16863.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1560</span> </span> <p class="card-text"><strong>References:</strong></p> <br>[1] Blasi, C., "Modeling and Simulation of Combustion Processes of Charring and Non-charring Solid Fules," Progress in Energy and Combustion Science, Vol. 19, No. 5, pp. 71-104, 1993. <br>[2] Blasi, C., "Heat, Momentum and Mass Transport through a Shrinking Biomass Particle exposed to Thermal Radiation," Chemical Engineering Science, Vol. 51, No. 7, pp. 1121-1132, 1996. <br>[3] Lee, C.
