Abstract

The ignition of individual droplets (radius 0.5–1.5 mm) of water–coal fuel based on water of different quality (industrial-grade, tap, and distilled water) in a flux of heated oxidant (at 700–1000 K) is studied experimentally. The influence of water quality on the ignition time and the time for complete combustion of the fuel droplet and also on the maximum combustion temperature is investigated. Experimental data are presented regarding the influence of the concentration of the different water samples in the fuel on its ignition. The delay of fuel ignition does not depend greatly on the water quality. (For industrial-grade, tap, and distilled water, the difference is no more than 10–15%.)
