Abstract
Agglomerated torrefied wood fuel was tested for its fuel properties and combustion characteristics. Torrefied wood was produced in a wood roaster, with three species (Pinus densiflora Siebold & Zucc., Quercus serrata Thumb. Ex Murray, Sinoarundinaria nigra var. henonis honda) that were torrefied at 220 °C for 180 s. After being torrefied, these powders were used as agglomerated torrefied wood-powder. Gelatin was used as binder, and linseed oil was spread on one side of each sample. All test samples were ignited and tested for carbon monoxide release and temperature variation. The agglomerated torrefied wood fuel showed 82% less carbon monoxide release in comparison to self-igniting briquettes. In particular, pine showed less CO release and mass loss. Also, pine and bamboo showed higher heat efficiency than the ignition coal. Therefore, using torrefied wood for agglomerated fuel reduced the carbon monoxide release and improved the heating efficiency of the ignition coal.
