Математическое моделирование воспламенения частицы водоугольного топлива

Abstract

The problem of particle ignition coal-water fuel (CWF) is solved. The equation of heat and mass transfer are considered both inside and outside the particle. The model takes into account the heterogeneous reaction inside the porous and homogeneous reaction outside the particle. According to the results of numerical simulation of the conditions for the ignition characteristics and particle CWF sufficiently typical combustion condition. The obtained values of the ignition delay time are in good agreement with published experimental data.
