A STUDY ON THE COMBUSTIBILITY OF TORREFIED WOOD OIL WATER MIXTURE DROPLETS/

This paper presents the results of an experimental study on the combus tion characteristics of torrefied wood (TW) slurries using suspended d roplets. The main factors that were investigated in this study are the initial diameter of the slurry droplets, the ambient temperature, the composition of the slurries including the solid content and the perce ntage content of a second liquid added to the parent slurry. The resul ts show a linear relationship between the square of the initial diamet er of the droplet and total combustion time for all kinds of TW-based slurries that were studied here but the slope of the line depends on t he composition of the slurries and the ambient temperature. Also, the combustibility of TW-based slurries was better than charcoal-based slu rries due to the better combustibility of TW. By adding a certain amou nt of a second liquid, especially water, to a TW-oil mixture, the comb ustibility of the resulting slurry was improved.
