Summary:Title screen
A mathematical model affording satisfactory representation of experimental values for the characteristics of the ignition of organic coal-water fuel droplets has been developed. Numerical investigations of the processes of ignition of droplets of the fuels based on typical wastes from dressing hard coals, enriching industrial oils, and water have been carried out. The delay times in ignition of organic coal-water fuel droplets with their radii varying from 0.25 to 1.5 mm, at oxidant fl ow velocity varying from 0.5 to 3 m/s and of its temperature varying from 700 to 1000 K, have been established. A satisfactory correspondence of the results of mathematical simulation to the familiar experimental data has been obtained. The possibility of using the ANSYS Fluent package for numerical simulation of the ignition of organic coal-water fuel droplets has been substantiated. The temperature fi elds of such droplets on ignition, as well as the coordinates of the zones of their intense chemical transformations, have been calculated. Prediction of the limiting conditions of stable ignition of organic coal-water fuels on relatively low-temperature heating has been made.
