The characteristics and conditions of the ignition of coal-water fuel droplets (WCF) in a surface coating with a thin layer of water last film have been determined experimentally. A significant impact on the dynamics of the water layer of the thermal preparation and ignition of the fuel particles has been established. It has been shown that the time of evaporation of water of the surface layer can take up to 50% of all of the induction period. The latter indicates the need to consider the existence of the surface of the film during the process modeling of ignition of coal-water particles.
