Mathematical and physical modeling of the coal–water fuel particle ignition with a liquid film on the surface

The results have been presented of the theoretical and experimental research of the ignition processes of single drops of coal–water fuel (CWF). Their surface is covered by a water film. The temperature of the environment Te has also been recorded and the main characteristics of the process — the times of complete evaporation of the water film (tewf)) and the ignition delays (tign). The errors in determining Te have not exceeded 5%. According to...
