This paper presents the results of an experimental study on the combustion characteristics of torrefied wood (TW) slurries using suspended droplets. 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 percentage content of a second liquid added to the parent slurry. The results show a linear relationship between the square of the initial diameter 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 the composition of the slurries and the ambient temperature. Also, the combustibility of TW‐based slurries was better than charcoal‐based slurries due to the better combustibility of TW. By adding a certain amount of a second liquid, especially water, to a TW‐oil mixture, the combustibility of the resulting slurry was improved.
