Heterogeneous droplets (multi-phase and multi-component slurries, emulsions and solutions) are a viable alternative to homogeneous fuels. A dispersed phase, e.g. water, brings about micro-explosive breakup, which significantly improves the efficiency of combustion of fuel compositions and reduces the concentrations of anthropogenic emissions (sulfur and nitrogen oxides). The micro-explosion of heterogeneous droplets holds great promise as a method of their secondary atomization during combustion at power plants, especially with relatively high-viscosity compositions (more than 100 mPa·s). In this paper, the micro-explosive breakup behavior of fuel droplets containing water of different quality was investigated. Ready-made vaporization centers in droplets in the form of solid particles or bubbles of air, gases, and vapors were found to be the most important factor. The droplet lifetime and breakup delays were determined, along with the impact of the composition of droplets on their heating dynamics. Approximations were obtained in the form of the critical bubble size as a function of the ambient gas temperature for two-liquid droplets containing the dispersed phase of different quality. The understanding of how the 0 % to 60 % variation in the mass concentration of solid particles affects the breakup delay times of slurry droplets is important for fuel-burning plants
