There are new types of composite fuels, such as coal-water slurry fuel and artificial composite liquid fuel that can be used to exploit the limited energy sources more effectively. Such composite fuels consist of coal fine particles and water (or liquid industrial waste). This paper presents the experimental study of the ignition of coal-water slurry fuel and artificial composite liquid fuel droplets during convective heating carried out at the National Research Tomsk Polytechnic University. The ignition delay time of the fuels has been determined when the heat source temperature varied from 350 to 600 °C. The analysis reported here has revealed droplet ignition mechanisms for four different fuel compositions.
