The formation of dispersed systems is associated with the adsorption of surfactants at the interface, which determines the stability of the phases. The study of the kinetics of this process, as well as possible technological influences on it, is important for the development of emulsification technology. A water-fuel emulsion allows you to significantly increase the efficiency of hydrocarbon fuels and significantly reduce the emission of harmful substances into the environment. The work investigates the influence of various factors on the process of crushing the dispersed phase of an emulsion during its boiling. Temperature is the main factor determining the fragmentation of dispersed water particles in fuel oil. This factor primarily determines the energy consumption for the preparation of stable water-oil fuel. The second factor is the tension at the interfacial boundary. The value of this coefficient is regulated by adding surfactants. We determine the sizes of water particles distributed in fuel oil by heating cold fuel oil with steam. They have a certain value. Based on this, the main parameters for regulating the process of preparing water-oil fuel resistant to stratification are the saturation pressure of the water phase, the corresponding system temperature, and the interfacial tension. Determining the optimal values of these parameters will allow rational use of energy in preparing liquid fuels.
