| 330 | _aThe coal-water slurries based on different types of coals and waste petrochemicals or other combustible liquids (CWSP) are very attractive for creation of cheap energetic fuel (for replacement of the coal and gas). Together with evident economic effect, the CWSP is perspective from ecological point of view. It contains a lot of water and therefore the air pollution by nitrogen and sulphur oxides is low. However, the energetic parameters of combustion of such slurry are enough far from excellence. Numerous publications were done during last years about development of new CWSP compositions as well as about improvements of its ignition and combustion techniques. The actual task is stable ignition of the slurry composition at low (critical) temperatures. In this work, we have investigated for a first time the influence of coagulation and splitting of fuel droplets onto the integral parameters of the ignition (using high-speed video-recording technique). These results clearly show the differences of ignition processes of single CWPS droplets and the aerosol flow ignition in combustion chamber. Our experiments gave the understanding of scales of co-influence of fuel droplets onto the ignition parameters. We have used the fuel compositions based on milled (particle size ~100 µm) lignite and bituminous coal, coal-processing wastes, waste industrial oils and mazut. The investigations were done for two-body system where droplet sizes were the same (0.5–1.5 mm) at every experiment. The temperature in the combustion chamber was in range from 600 K to 1200 K. Some sequences of coagulation/splitting were observed: coagulation/splitting inside the combustion chamber; droplet coagulation before injection into the combustion volume. | ||
