| Tóm tắt: | Заглавие с экрана High concentrations of major anthropogenic gas emissions, such as sulfur, nitrogen and carbon oxides, are a key factor in air pollution in regions with intensive coal burning. Therefore, today the tasks of optimizing coal burning with minimal negative impact on the environment are relevant. The study presented the findings of experimental research on the behavior of droplets colliding with the surfaces of particles and substrates made of promising components of oil-water suspensions. The coal particles used had varying degrees of metamorphism and different levels of surface wettability. The properties of the resulting child droplets were calculated and maps were created to illustrate the various modes of interaction between droplets and particles. The obtained equations allow for predicting slight shifts in the boundary positions for different components of fuel mixtures. An increase in the values of the contact angle, lower values of the Weber number are required to implement the fracture mode. Additionally, differences in the characteristics of secondary crushing of droplets during the interaction with particles were identified Текстовый файл |
