Mathematical modeling of drying of coal particles in the gas stream

Abstract

Physical-mathematical model of drying of coal particles in the gas stream and the results of calculating the drying of the particles of brown coal in a drying tube are presented. It is shown that for the drying of coal can be used superheated water vapor. Thermodynamic model of drying of a particle in a drying tube are proposed. It allows to conduct a preliminary assessment of parameters of drying process.
