An experimental study of the ignition and combustion characteristics of single droplets of biochar-glycerol-water slurry fuels

The ignition and combustion behaviour of single droplets of biochar-glycerol-water slurry fuels was experimentally investigated. A pine sawdust biochar with a median particle size (D50) of approximately 12 µm was used. The slurry fuels with a constant biochar loading of 42wt% and glycerol/water ratios varying from 0 to 0.5 by weight were prepared. A single droplet of a slurry fuel with diameter ranging from 0.5 mm to 2.0 mm was suspended on a...
