| Summary: | Title screen In this study, the main ignition and combustion characteristics have been compared for droplet groups of a coal-water slurry containing petrochemicals (CWSP), as well as oil, surrounded by water droplets. Thus, in a combustion chamber, we simulated the ignition and combustion conditions of a heterogeneous fuel aerosol that can be formed when jets of different liquids cross or when multi-component flows delaminate. It was shown that a decrease in the distance between droplets (from 10 mm to 2 mm, i.e. to the typical fuel droplet size) reduces the gas-phase and heterogeneous ignition delay times of oil and CWSP by 30% on average. The evaporation times of water droplets decrease by approximately 25%, if the distance between them increases in the combustion chamber. It was established that the ignition delay times of oil and coal-water slurry containing petrochemicals increased by 20–40% and 40–70%, respectively, when a combustible liquid droplet was in the center with six water droplets around it. The experimental results are a database for the development of efficient technologies of injecting multi-component fuel into combustion chambers.
